Quick answer: Use ob when the clause means whether something is true; use wenn when the clause gives the condition under which another action occurs. Both normally introduce German subordinate clauses with the finite verb at the end. Do not infer the answer from the English word if alone.
An English sentence containing if does not tell a translator which German conjunction to use. The first decision is whether the clause is a concealed question about truth or a condition that makes something else happen.
Ob introduces a yes-or-no alternative being considered, asked, checked, known or unknown. Wenn introduces a dependency: if or whenever one circumstance holds, another circumstance follows. English can hide both relations behind the same small word.
The problem often becomes visible in email, travel planning, safety instructions, admissions forms, customer support and reported speech: ‘Let me know if the parcel arrives’ can be ambiguous until the writer’s intention is understood.
Search topics covered: German ob vs wenn, German if versus whether, indirect questions German word order, whether in German, German wenn conditional clauses. This is a focused educational guide for readers translating German into English or English into German. It is not a replacement for verified source context when the original is ambiguous.
What this guide solves — and what it does not
Translate German ob as an embedded yes-or-no uncertainty, while identifying wenn as a condition or recurring time. This guide owns indirect questions and conditional clause selection, not the broader als/wenn/wann time distinction.
- ob = whether / an indirect yes-no question
- wenn = if / on condition that / whenever
- wann = when in a time question (adjacent but not this page’s owner)
The central problem is not a shortage of dictionary equivalents. It is a choice about the relationship the words encode. A reader must be able to distinguish what is possible from what has occurred, what was chosen from what was arranged, or what is questioned from what is conditional. A translation that sounds smooth but assigns the wrong action, actor, scope or certainty is not a faithful translation.
Start with the simple contrast in the table above, and then verify it against each full sentence. A reliable approach separates three levels: the grammatical form in German, the relation expressed by that form, and the natural English wording suited to the context. Do not collapse these three levels into a single word-for-word substitution.
First principles: the information that must survive translation
1. The meaning belongs to a relationship, not one word
A small grammatical form can determine whether the speaker knows, chooses, permits, succeeds, imagines or refers to something. A sentence should be interpreted as an event or proposition with participants, time and logical relationships rather than as a sequence of isolated bilingual words.
Apply that principle to German by asking: Is there a hidden yes-or-no question? Then make two short English drafts: one literal enough to reveal the original structure, and one idiomatic enough for a real reader. Compare the facts each draft commits you to. The preferred version is the one that both sounds natural and preserves the exact relation. If a key feature is missing, note it in the margin before revising.
2. The reader’s question comes before the dictionary choice
A good translation answers the reader’s actual question: What happened? What is still unknown? Who decided? Which one is being discussed? If your English produces a different answer from the source language, it may be grammatically elegant but communicatively wrong.
Apply that principle to German by asking: Can English if become whether without changing the meaning? Then make two short English drafts: one literal enough to reveal the original structure, and one idiomatic enough for a real reader. Compare the facts each draft commits you to. The preferred version is the one that both sounds natural and preserves the exact relation. If a key feature is missing, note it in the margin before revising.
3. Context limits apparently interchangeable English words
English can or if or what often covers several separate relations. A dictionary supplies candidate equivalents; the surrounding verbs, prepositions, negation, tense and discourse purpose select the one the writer intended. One word can be an excellent translation in one sentence and misleading in another.
Apply that principle to German by asking: Does the main action depend on this clause being fulfilled? Then make two short English drafts: one literal enough to reveal the original structure, and one idiomatic enough for a real reader. Compare the facts each draft commits you to. The preferred version is the one that both sounds natural and preserves the exact relation. If a key feature is missing, note it in the margin before revising.
4. Evidence and responsibility should not be invented
Translators must not insert a decision-maker, legal authority, personal motive, successful outcome, guaranteed fact or identified person not actually supported by the source. If the text deliberately leaves something implicit, natural English can preserve that restraint.
Apply that principle to German by asking: Is the speaker asking about a fact or specifying what will happen? Then make two short English drafts: one literal enough to reveal the original structure, and one idiomatic enough for a real reader. Compare the facts each draft commits you to. The preferred version is the one that both sounds natural and preserves the exact relation. If a key feature is missing, note it in the margin before revising.
5. Grammar creates operational consequences
An error may change who receives an instruction, whether an action is required, whether a condition triggers a response, or whether the text reports an accomplished result. In public, medical, institutional and work settings these are meaningful differences.
Apply that principle to German by asking: Does whenever express a repeated circumstance? Then make two short English drafts: one literal enough to reveal the original structure, and one idiomatic enough for a real reader. Compare the facts each draft commits you to. The preferred version is the one that both sounds natural and preserves the exact relation. If a key feature is missing, note it in the margin before revising.
6. Naturalness follows accuracy rather than replacing it
Literal English is a useful diagnostic draft but rarely the final destination. Once the source relationship is secure, choose a readable target-language sentence, adjusting word order, articles or voice where necessary without shifting agency, time, reference or condition.
Apply that principle to German by asking: Is there an embedded W-question requiring wann, wo or wie instead? Then make two short English drafts: one literal enough to reveal the original structure, and one idiomatic enough for a real reader. Compare the facts each draft commits you to. The preferred version is the one that both sounds natural and preserves the exact relation. If a key feature is missing, note it in the margin before revising.
7. Negative and completed forms deserve a separate pass
Before finalising any sentence, isolate negatives, completed or ongoing forms, quantifiers and subordinate clauses. These small elements can reverse a commitment, change a habit into a single event or move the negation from knowledge to action.
Apply that principle to German by asking: Where is the finite German verb inside the subordinate clause? Then make two short English drafts: one literal enough to reveal the original structure, and one idiomatic enough for a real reader. Compare the facts each draft commits you to. The preferred version is the one that both sounds natural and preserves the exact relation. If a key feature is missing, note it in the margin before revising.
8. Verification requires a back-translation question
After drafting, ask what a careful target-language reader would believe to be true, required, permitted or intended. Compare this with the source. If the two implied stories diverge, repair the translation rather than defending an attractive phrase.
Apply that principle to German by asking: Could both readings exist in the English source? If so, mark ambiguity. Then make two short English drafts: one literal enough to reveal the original structure, and one idiomatic enough for a real reader. Compare the facts each draft commits you to. The preferred version is the one that both sounds natural and preserves the exact relation. If a key feature is missing, note it in the margin before revising.
A repeatable twelve-stage translation method
Step 1: Identify the document’s communicative job
Name whether the text is explaining, requesting, reporting, instructing or narrating. German sentences may carry the same vocabulary but different communicative functions; a reported enquiry should not become a conditional instruction.
Step 2: Underline the target construction
Mark the whole expression, including surrounding articles, particles, prepositions, auxiliary verbs and negative forms. A single highlighted word can conceal where the grammatical meaning begins and ends.
Step 3: Locate the participants and the action
Write who is acting, who can act, who makes a decision, and what is happening or being referred to. If one participant is not specified, leave that uncertainty visible rather than making one up.
Step 4: Determine the main logical relation
Apply the primary contrast: ob = whether / an indirect yes-no question; wenn = if / on condition that / whenever; wann = when in a time question (adjacent but not this page’s owner). State the selected reading aloud in a complete English sentence before trying to polish style.
Step 5: Identify time, aspect and completion
Check whether the form expresses a present standing rule, a future plan, a settled decision, a past successful event, a habitual condition or an uncertain fact. These distinctions may require more than one English word.
Step 6: Scope negation accurately
Ask what is being negated: the event, the possibility, the permission, the decision, the knowledge, or a reference. A fluent sentence that negates the wrong proposition changes the reader’s next action.
Step 7: Check complement structure and word order
Confirm that the relevant subordinate verbs, particles, articles, infinitive linkers or agreement endings are where the source language requires them. Rebuilding these structures is often a more reliable repair than swapping an English synonym.
Step 8: Draft a literal diagnostic gloss
Write a brief functional gloss such as ‘whether’, ‘only if’, ‘managed to’, ‘the one who’, or ‘the decision was settled’. The gloss is a temporary instrument, not necessarily the final reader-facing text.
Step 9: Rewrite in natural target-language English
Choose English that would genuinely appear in a manual, conversation, announcement or report. A noun phrase may become a clause, and an impersonal result may become a schedule, provided the source relation remains unchanged.
Step 10: Run the counterexample test
Replace the construction mentally with its nearby alternative. Would the sentence now claim a different actor, condition, outcome or referent? If yes, you have identified the distinction the final text must keep.
Step 11: Practise a realistic recipient response
Imagine what a reader would do after seeing the translation: ask a question, enter a room, wait for a decision, regard a success as completed, or choose a particular object. An incorrect response exposes a meaning error.
Step 12: Record a correction rule for reuse
Keep the problematic source phrase, your corrected translation, a one-sentence explanation and an example with different vocabulary. This creates a reusable understanding rather than a fragile memorised pair.
Worked examples: source, natural English and the decision behind it
These examples are deliberately organised around distinct communicative situations rather than a disconnected list of flashcards. Read the full source, compare the tempting alternative with the recommended version, and check the explanation. The aim is to recognise the relationship when the vocabulary changes.
Example 1: The uncertain arrival
German source: Ich weiß nicht, ob er heute kommt.
Preferred English: I don’t know whether he is coming today.
Tempting but misleading reading: I don’t know when he comes.
Why: The unknown fact is his attendance, not the schedule; the clause reports a yes/no uncertainty. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 2: The conditional arrival
German source: Wenn er heute kommt, beginnen wir früher.
Preferred English: If he comes today, we’ll start earlier.
Tempting but misleading reading: Whether he comes today, we’ll start earlier.
Why: His coming triggers an earlier start; the sentence does not report a hidden question. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 3: Checking punctuality
German source: Kannst du prüfen, ob der Zug pünktlich ist?
Preferred English: Can you check whether the train is on time?
Tempting but misleading reading: Can you check when the train is on time?
Why: The checker must establish a true-or-false status. Pünktlich is a condition to verify. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 4: Delaying for a train
German source: Wenn der Zug Verspätung hat, warten wir.
Preferred English: If the train is delayed, we’ll wait.
Tempting but misleading reading: Whether the train is delayed, we’ll wait.
Why: Waiting is conditional on delay, so wenn is the connective with the operational consequence. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 5: Fronted indirect question
German source: Ob er teilnehmen kann, ist noch unklar.
Preferred English: Whether he can take part is still unclear.
Tempting but misleading reading: If he can take part, it is still unclear.
Why: The entire fronted ob-clause functions as what remains undecided. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 6: Available time
German source: Wenn ich Zeit habe, rufe ich dich an.
Preferred English: I’ll call you if I have time.
Tempting but misleading reading: I’ll call you whether I have time.
Why: Availability controls the promise; it is not a question being investigated. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 7: Door status
German source: Bitte schau nach, ob die Tür abgeschlossen ist.
Preferred English: Please check whether the door is locked.
Tempting but misleading reading: Please check if the door becomes locked.
Why: The task is verification, not describing a circumstance in which to check. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 8: Door instruction
German source: Wenn die Tür abgeschlossen ist, benutze den Seiteneingang.
Preferred English: If the door is locked, use the side entrance.
Tempting but misleading reading: Whether the door is locked, use the side entrance.
Why: The user needs a contingent instruction triggered by the door’s state. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 9: Choice of route
German source: Wir müssen entscheiden, ob wir zu Fuß gehen.
Preferred English: We need to decide whether to walk.
Tempting but misleading reading: We need to decide when we walk.
Why: A decision considers an alternative; ob identifies the option under consideration. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 10: Weather dependency
German source: Wenn es schneit, fällt der Ausflug aus.
Preferred English: If it snows, the excursion is cancelled.
Tempting but misleading reading: Whether it snows, the excursion is cancelled.
Why: Cancellation has a stated condition. The weather is not merely an unresolved yes/no question. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 11: Depends on rain
German source: Es hängt davon ab, ob es morgen regnet.
Preferred English: It depends on whether it rains tomorrow.
Tempting but misleading reading: It happens whenever it rains tomorrow.
Why: The predicate depends on points toward a choice between possible states. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 12: Concession
German source: Auch wenn es regnet, gehen wir los.
Preferred English: Even if it rains, we’re setting off.
Tempting but misleading reading: Even whether it rains, we’re setting off.
Why: Auch wenn acknowledges a condition without letting it stop the planned action. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 13: Knowing a booking exists
German source: Ich möchte wissen, ob noch Plätze frei sind.
Preferred English: I want to know whether places are still available.
Tempting but misleading reading: I want to know if places become free.
Why: This requests information about availability, especially relevant to tickets and enrolments. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 14: Conditional booking
German source: Wenn Plätze frei sind, buche ich zwei.
Preferred English: If seats are available, I’ll book two.
Tempting but misleading reading: Whether seats are available, I’ll book two.
Why: Booking occurs only under the availability condition. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 15: Embedded modal
German source: Sie fragt, ob du morgen helfen kannst.
Preferred English: She asks whether you can help tomorrow.
Tempting but misleading reading: She asks whenever you can help tomorrow.
Why: The modal kannst sits at the end, and the question concerns ability on that day. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 16: Conditional modal
German source: Wenn du morgen helfen kannst, sag bitte Bescheid.
Preferred English: If you can help tomorrow, please let me know.
Tempting but misleading reading: Whether you can help tomorrow, tell me.
Why: The recipient should reply in a particular case; the if-clause limits the request. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 17: Independence of the answer
German source: Ob er zustimmt oder nicht, müssen wir weiterplanen.
Preferred English: Whether he agrees or not, we must keep planning.
Tempting but misleading reading: If he agrees or not, we must keep planning.
Why: The paired alternatives show a decision that remains in force regardless of the answer. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 18: False analogy
German source: Er tut so, als ob er alles wüsste.
Preferred English: He acts as if he knew everything.
Tempting but misleading reading: He acts whether he knew everything.
Why: Als ob expresses an apparent or unreal comparison and is a separate fixed construction. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 19: W-question control
German source: Ich weiß nicht, wann sie zurückkommt.
Preferred English: I don’t know when she returns.
Tempting but misleading reading: I don’t know whether she returns.
Why: Wann requests a time, not a yes-or-no answer; the distinction prevents overusing ob. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 20: Schedule condition
German source: Wenn sie zurückkommt, sprechen wir darüber.
Preferred English: When she returns, we’ll discuss it.
Tempting but misleading reading: Whether she returns, we’ll discuss it.
Why: A future time may be presented as the trigger for the main action, so wenn can translate as when. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 21: Reported inquiry
German source: Die Kundin fragte, ob eine Rückgabe möglich sei.
Preferred English: The customer asked whether a return was possible.
Tempting but misleading reading: The customer asked whenever a return was possible.
Why: This reports a yes/no enquiry, not a condition for completing a return. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 22: Refund policy
German source: Wenn der Artikel beschädigt ist, erstatten wir den Kaufpreis.
Preferred English: If the item is damaged, we refund the price.
Tempting but misleading reading: Whether the item is damaged, we refund the price.
Why: A rule has an applicability condition; wrongly using whether would misstate the policy. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 23: No certainty
German source: Es ist ungewiss, ob der Vertrag verlängert wird.
Preferred English: It is uncertain whether the contract will be renewed.
Tempting but misleading reading: It is uncertain when the contract will be renewed.
Why: The extension itself is uncertain, not just its date. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 24: Organising two meanings
German source: Wenn ich wüsste, ob er kommt, könnte ich planen.
Preferred English: If I knew whether he was coming, I could plan.
Tempting but misleading reading: Whether I knew if he came, I could plan.
Why: The outer wenn is hypothetical; the inner ob introduces the information the speaker lacks. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 25: Neutral information request
German source: Sagen Sie mir bitte, ob der Raum verfügbar ist.
Preferred English: Please tell me whether the room is available.
Tempting but misleading reading: Tell me whenever the room is available.
Why: The polite request seeks one fact about current room availability. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 26: Recurring habit
German source: Wenn wir Ferien haben, besuchen wir die Großeltern.
Preferred English: Whenever we’re on holiday, we visit our grandparents.
Tempting but misleading reading: Whether we’re on holiday, we visit our grandparents.
Why: The sentence describes a repeated time-and-condition pattern rather than a question. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 27: Uncertainty with negatives
German source: Sie weiß nicht, ob die Nachricht angekommen ist.
Preferred English: She doesn’t know whether the message has arrived.
Tempting but misleading reading: She doesn’t know if the message will arrive each time.
Why: The negative is on knowledge, not the arrival event; ob preserves the factual uncertainty. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Example 28: Conditional negative
German source: Wenn die Nachricht nicht ankommt, schicke ich sie erneut.
Preferred English: If the message doesn’t arrive, I’ll send it again.
Tempting but misleading reading: Whether the message doesn’t arrive, I’ll send it again.
Why: The resend instruction is triggered by failure of delivery and must not be presented as a mere enquiry. The translator should preserve that distinction even when a shorter English phrase appears more natural on first inspection.
Failure modes: diagnose the wrong mental move
Most recurring errors are generated by a repeatable wrong assumption. Do not only cross out the incorrect form: identify the assumption, replace it with a better decision test, and then practise it in a fresh sentence.
Error 1: Replacing every English if with wenn
Misleading form or gloss: Ich weiß nicht, wenn er kommt.
Repair: Ich weiß nicht, ob er kommt.
The wrong connector turns an indirect yes/no question into a malformed time-or-condition relation. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Error 2: Replacing every if with ob
Misleading form or gloss: Ob es regnet, bleiben wir drinnen.
Repair: Wenn es regnet, bleiben wir drinnen.
Staying indoors is conditional; ob cannot function as the condition in this clause. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Error 3: Retaining main-clause order
Misleading form or gloss: Ich frage, ob er kommt morgen.
Repair: Ich frage, ob er morgen kommt.
Ob introduces a subordinate clause and the finite verb belongs at its end. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Error 4: Using ob to ask when
Misleading form or gloss: Ich weiß nicht, ob der Zug kommt at 8.
Repair: Ich weiß nicht, wann der Zug kommt.
A request for a time needs wann; the wording ‘at 8’ should be translated rather than pasted. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Error 5: Ignoring the second layer
Misleading form or gloss: Wenn ich weiß, wenn sie kommt, rufe ich an.
Repair: Wenn ich weiß, ob sie kommt, rufe ich an.
One sentence can contain a conditional outer clause and a hidden yes/no inner question. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Error 6: Forgetting alternative structure
Misleading form or gloss: Ich weiß nicht, wenn er ja oder nein sagt.
Repair: Ich weiß nicht, ob er ja oder nein sagt.
Where yes or no are the answers, ob introduces the alternative correctly. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Error 7: Confusing repeated when with reported whether
Misleading form or gloss: Ob ich frei hatte, ging ich schwimmen.
Repair: Wenn ich frei hatte, ging ich schwimmen.
A past habit may use wenn, not ob, because no question is embedded. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Error 8: Treating als ob as a normal question
Misleading form or gloss: Er klingt, ob er müde wäre.
Repair: Er klingt, als ob er müde wäre.
An as-if comparison requires the larger construction als ob. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Error 9: Omitting the comma
Misleading form or gloss: Ich frage mich ob er kommt.
Repair: Ich frage mich, ob er kommt.
Comma punctuation signals the subordinate clause and improves readability. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Error 10: Claiming all ob clauses are questions with a question mark
Misleading form or gloss: Ich weiß nicht, ob er kommt?
Repair: Ich weiß nicht, ob er kommt.
The whole utterance is declarative even though it embeds a yes/no question. The repair changes an interpretable feature of the utterance, not just its appearance. Recheck the role of the surrounding words before memorising the corrected form. Ask whether an English reader would now understand the intended fact, person, action or condition in the same way as the source reader.
Practice: retrieve the rule rather than guess a word
For each item, first hide the answer. Translate the short source, state why this construction was chosen, then expose the answer. Change one detail in the source and see whether the same reasoning survives. This progression tests comprehension, correction and transfer instead of only recognition.
Practice 1: The uncertain arrival
Prompt: Translate Ich weiß nicht, ob er heute kommt. for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.
Answer: I don’t know whether he is coming today. Explanation: The unknown fact is his attendance, not the schedule; the clause reports a yes/no uncertainty. A common incorrect direction would be: I don’t know when he comes.. For transfer, replace one noun or verb in the source with a familiar equivalent while keeping the grammatical pattern. Explain whether the same decision rule still applies; if you cannot do that, revisit the worked example.
Practice 2: The conditional arrival
Prompt: Translate Wenn er heute kommt, beginnen wir früher. for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.
Answer: If he comes today, we’ll start earlier. Explanation: His coming triggers an earlier start; the sentence does not report a hidden question. A common incorrect direction would be: Whether he comes today, we’ll start earlier.. For transfer, replace one noun or verb in the source with a familiar equivalent while keeping the grammatical pattern. Explain whether the same decision rule still applies; if you cannot do that, revisit the worked example.
Practice 3: Checking punctuality
Prompt: Translate Kannst du prüfen, ob der Zug pünktlich ist? for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.
Answer: Can you check whether the train is on time? Explanation: The checker must establish a true-or-false status. Pünktlich is a condition to verify. A common incorrect direction would be: Can you check when the train is on time?. For transfer, replace one noun or verb in the source with a familiar equivalent while keeping the grammatical pattern. Explain whether the same decision rule still applies; if you cannot do that, revisit the worked example.
Practice 4: Delaying for a train
Prompt: Translate Wenn der Zug Verspätung hat, warten wir. for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.
Answer: If the train is delayed, we’ll wait. Explanation: Waiting is conditional on delay, so wenn is the connective with the operational consequence. A common incorrect direction would be: Whether the train is delayed, we’ll wait.. For transfer, replace one noun or verb in the source with a familiar equivalent while keeping the grammatical pattern. Explain whether the same decision rule still applies; if you cannot do that, revisit the worked example.
Practice 5: Fronted indirect question
Prompt: Translate Ob er teilnehmen kann, ist noch unklar. for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.
Answer: Whether he can take part is still unclear. Explanation: The entire fronted ob-clause functions as what remains undecided. A common incorrect direction would be: If he can take part, it is still unclear.. For transfer, replace one noun or verb in the source with a familiar equivalent while keeping the grammatical pattern. Explain whether the same decision rule still applies; if you cannot do that, revisit the worked example.
Practice 6: Available time
Prompt: Translate Wenn ich Zeit habe, rufe ich dich an. for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.
Answer: I’ll call you if I have time. Explanation: Availability controls the promise; it is not a question being investigated. A common incorrect direction would be: I’ll call you whether I have time.. For transfer, replace one noun or verb in the source with a familiar equivalent while keeping the grammatical pattern. Explain whether the same decision rule still applies; if you cannot do that, revisit the worked example.
Practice 7: Door status
Prompt: Translate Bitte schau nach, ob die Tür abgeschlossen ist. for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.
Answer: Please check whether the door is locked. Explanation: The task is verification, not describing a circumstance in which to check. A common incorrect direction would be: Please check if the door becomes locked.. For transfer, replace one noun or verb in the source with a familiar equivalent while keeping the grammatical pattern. Explain whether the same decision rule still applies; if you cannot do that, revisit the worked example.
Practice 8: Door instruction
Prompt: Translate Wenn die Tür abgeschlossen ist, benutze den Seiteneingang. for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.
Answer: If the door is locked, use the side entrance. Explanation: The user needs a contingent instruction triggered by the door’s state. A common incorrect direction would be: Whether the door is locked, use the side entrance.. For transfer, replace one noun or verb in the source with a familiar equivalent while keeping the grammatical pattern. Explain whether the same decision rule still applies; if you cannot do that, revisit the worked example.
Practice 9: Choice of route
Prompt: Translate Wir müssen entscheiden, ob wir zu Fuß gehen. for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.
Answer: We need to decide whether to walk. Explanation: A decision considers an alternative; ob identifies the option under consideration. A common incorrect direction would be: We need to decide when we walk.. For transfer, replace one noun or verb in the source with a familiar equivalent while keeping the grammatical pattern. Explain whether the same decision rule still applies; if you cannot do that, revisit the worked example.
Practice 10: Weather dependency
Prompt: Translate Wenn es schneit, fällt der Ausflug aus. for a reader who does not know German. Decide what an overly literal or careless translation would imply. Before viewing the answer, identify the action, reference or logical relation, and name the source-language clue that settles the choice.

Transfer: five real-world editing situations
Scenario 1: A public notice
A notice can create or remove a reader’s responsibility. Determine whether the German source expresses a condition, a prohibition, a settled rule, a permission, or a selected person. Keep the operative content in the English sentence, and avoid replacing it with a vague ‘can’, ‘if’, ‘which’ or ‘decided’. Compare the final draft with an alternative version and say how a visitor would act differently.
Apply this scenario to two of the numbered German worked examples. First describe the mistaken reader action under the rejected reading. Next justify the preferred English with a concrete feature of the source sentence. Finally write a variant with new vocabulary and check that the same semantic distinction holds. This is an application exercise, not a request to repeat the table mechanically.
Scenario 2: A personal message
In personal communication, the audience may be forgiving about tone but sensitive to who chose what or what the speaker actually knows. Preserve that interpersonal relationship before smoothing the English. A message that turns a question into a prediction, or a shared arrangement into a personal order, may sound natural but misrepresent the sender.
Apply this scenario to two of the numbered German worked examples. First describe the mistaken reader action under the rejected reading. Next justify the preferred English with a concrete feature of the source sentence. Finally write a variant with new vocabulary and check that the same semantic distinction holds. This is an application exercise, not a request to repeat the table mechanically.
Scenario 3: An educational explanation
A school handout should demonstrate the rule with at least two contrasting examples rather than stating an equivalence list. Give the learner one correctly translated sample, then a minimal pair where the small form changes the answer. Ask them to explain what changed and provide a new example from their own subject vocabulary.

Next justify the preferred English with a concrete feature of the source sentence. Finally write a variant with new vocabulary and check that the same semantic distinction holds. This is an application exercise, not a request to repeat the table mechanically.
Scenario 4: A workplace update
Workplaces care about completion, assignment, deadlines and permissions. Do not write that a task was accomplished if the source only says it was possible, and do not identify a specific manager if the source merely reports an arrangement. If the original is deliberately impersonal, consider whether a neutral English passive, ‘scheduled’ or an indirect-question construction is safest.

Next justify the preferred English with a concrete feature of the source sentence. Finally write a variant with new vocabulary and check that the same semantic distinction holds. This is an application exercise, not a request to repeat the table mechanically.
Scenario 5: An online translation check
Machine-assisted drafts can be a useful first pass, but fluent English alone does not establish fidelity. Check the construction in the source, verify the relevant grammatical relation and ask what new information the English adds. Flag unresolved ambiguity rather than silently choosing an interpretation. The result should be a documented correction a second editor can understand.

Frequently asked questions
Does ob always translate as whether?
Often, but natural English sometimes prefers if. The German grammar role is still an embedded yes/no alternative.
Does wenn mean when or if?
Both, depending on whether the clause presents a condition, a recurring event, or an anticipated future occurrence.
Where does the verb go after ob?
In an ordinary subordinate clause, the finite verb goes to the end; with a modal it normally follows the infinitive.
Can ob start a sentence?
Yes: Ob das stimmt, weiß ich nicht. The entire fronted clause is what the speaker does not know.
What does ‘es kommt darauf an, ob’ mean?
It means ‘it depends on whether’; the construction weighs an unknown yes/no fact.
Is ‘als ob’ the same as ob?
No. Als ob creates an as-if comparison; it is not the standard indirect question marker.
When does wenn mean whenever?
When a repeated condition or time is described, such as a habitual action during holidays.
What if English ‘let me know if’ is ambiguous?
Decide whether the writer wants a yes/no report now or notification only when a future event occurs; ask for context if necessary.
What is the relationship to wann?
Wann is the question word ‘when’ for an unknown time; wenn is conditional or temporal, and ob concerns yes/no status.
Can ob appear inside a wenn sentence?
Yes, e.g. Wenn ich wüsste, ob …, könnte ich …. Each connector has its own job.
Editorial checklist for an independent final pass
- 1. Is there a hidden yes-or-no question?
- 2. Can English if become whether without changing the meaning?
- 3. Does the main action depend on this clause being fulfilled?
- 4. Is the speaker asking about a fact or specifying what will happen?
- 5. Does whenever express a repeated circumstance?
- 6. Is there an embedded W-question requiring wann, wo or wie instead?
- 7. Where is the finite German verb inside the subordinate clause?
- 8. Could both readings exist in the English source? If so, mark ambiguity.
- 9. Would a reader act differently under the alternative translation?
- 10. Does the text need a question mark or merely an embedded clause?
If a draft fails the checklist, repair the grammatical decision before polishing style. Read the revised English without looking at the source; ask whether a reader would infer the same event, reference, condition, agency and time. Retain a clear wording where context is insufficient and seek clarification for consequential uncertainty.
