Top Ways to Translate Correctly | Korean -아/어서 vs -(으)니까: Reasons and Requests

Korean has several ways to link a reason to its result. The endings -아/어서 and -(으)니까 are both often translated as because, so or since, but they are not freely interchangeable. The key translation question is whether the reason describes what caused a situation or supports what the speaker wants the listener to do.

Searches for Korean 아서 versus 니까 translation, Korean because grammar and Korean reason connectors usually arise when a learner can translate every word yet cannot explain why one sentence sounds natural and another does not. In particular, -아/어서 generally does not introduce the reason for an ensuing direct command or let’s-suggestion, while -(으)니까 commonly can. This is a usable first distinction, not an absolute replacement for reading the wider context.

This guide provides a plain-English answer, a first-principles cause-and-reason model, a twelve-step decision workflow, Korean–English worked examples, pitfalls, guided exercises and next learning routes. Its canonical focus is reason-connective choice and speech-act force—not honorific speech levels or 은/는 versus 이/가, which belong to separate series owners.

The real translation problem

A student translates 비가 와서 못 갔어요 as ‘It rained, so I couldn’t go’ and does well. Later the same student writes 추워서 문을 닫으세요 for ‘It’s cold, so please close the door.’ The difficulty is not the vocabulary for cold, door or close. It is the connection between a reason and an imperative. A reliable translator has to read the entire sentence before deciding which linking form is doing the work.

For learners and translators working between Korean and English in conversation, study, customer messages, classroom instructions and everyday explanations, the practical job is to distinguish a Korean causal link describing an event from a reason supporting a decision, request, suggestion or instruction. A helpful translator does not ask only “What does this word mean?” The better question is “What exact distinction has the source made, and what will the English reader believe after reading my sentence?” This question protects chronology, certainty, the identities involved and the action the speaker intends.

The answer in one minute

• distinguish a Korean causal link describing an event from a reason supporting a decision, request, suggestion or instruction.
• Read the whole source sentence and its immediate context.
• Separate grammatical form from the communicative action.
• Draft natural English and verify that nothing factual was added or lost.
• Practise contrasting examples rather than memorising a single English equivalent.

First principles: the distinctions that make the translation work

1. Cause and justification are related but different

An explanation may report why an outcome happened: I stayed in because it rained. A justification gives a reason to make a choice: It’s raining, so take an umbrella. English can use because for both, whereas Korean connector choice often makes the difference more visible.

Why this matters in a translation: a reader who receives the wrong version of cause and justification are related but different may infer a different world from the one the writer described. Before polishing vocabulary, write a one-sentence account of the actual relationship in the source. Then ask what an ordinary English reader needs to recover it. When the literal target overstates what happened, choose a meaning-preserving paraphrase and keep the grammatical note in your working rather than in the finished sentence.

2. -아/어서 core use

Attached to the preceding predicate, -아/어서 commonly describes the reason for an event or state; it also has a sequential use in other environments. Translators must decide whether an occurrence is causal or chronological from the two clauses.

Why this matters in a translation: a reader who receives the wrong version of -아/어서 core use may infer a different world from the one the writer described. Before polishing vocabulary, write a one-sentence account of the actual relationship in the source. Then ask what an ordinary English reader needs to recover it. When the literal target overstates what happened, choose a meaning-preserving paraphrase and keep the grammatical note in your working rather than in the finished sentence.

3. -(으)니까 core use

This form readily gives a reason that supports a speaker’s judgement, suggestion, request or command. The exact English equivalent may be ‘since’, ‘because’, ‘so’, or a two-sentence explanation.

Why this matters in a translation: a reader who receives the wrong version of -(으)니까 core use may infer a different world from the one the writer described. Before polishing vocabulary, write a one-sentence account of the actual relationship in the source. Then ask what an ordinary English reader needs to recover it. When the literal target overstates what happened, choose a meaning-preserving paraphrase and keep the grammatical note in your working rather than in the finished sentence.

4. Final-clause function

The critical diagnostic is often the ending of the second clause: statement, question, request, imperative or invitation. The speaker’s communicative action can constrain which Korean reason form is natural.

Why this matters in a translation: a reader who receives the wrong version of final-clause function may infer a different world from the one the writer described. Before polishing vocabulary, write a one-sentence account of the actual relationship in the source. Then ask what an ordinary English reader needs to recover it. When the literal target overstates what happened, choose a meaning-preserving paraphrase and keep the grammatical note in your working rather than in the finished sentence.

5. Politeness is a separate layer

A sentence may have a polite ending while retaining a causal connector. Do not confuse the listener-directed politeness of -세요 or -어요 with the logical relation contributed by -아/어서 and -(으)니까.

Why this matters in a translation: a reader who receives the wrong version of politeness is a separate layer may infer a different world from the one the writer described. Before polishing vocabulary, write a one-sentence account of the actual relationship in the source. Then ask what an ordinary English reader needs to recover it. When the literal target overstates what happened, choose a meaning-preserving paraphrase and keep the grammatical note in your working rather than in the finished sentence.

6. Sequence versus reason

In sentences such as 친구를 만나서 반가웠어요, the connection between meeting someone and being pleased is causal and closely linked to sequence. The English target can naturally say ‘I was glad to meet my friend’ without a rigid because.

Why this matters in a translation: a reader who receives the wrong version of sequence versus reason may infer a different world from the one the writer described. Before polishing vocabulary, write a one-sentence account of the actual relationship in the source. Then ask what an ordinary English reader needs to recover it. When the literal target overstates what happened, choose a meaning-preserving paraphrase and keep the grammatical note in your working rather than in the finished sentence.

Eight contrasts worth learning before you translate

1. -아/어서 plus statement

commonly states cause or linked occurrence. Translate the event relation rather than searching for a single fixed English conjunction.

The decision rule is not to match one form with one stock English word, but to test what information the form contributes. In a short source fragment, some choices remain open; a longer paragraph can settle them. Record both possibilities when needed, identify what additional context would decide between them, and never present a plausible guess as though the original made it explicit.

2. -(으)니까 plus directive

often supplies a reason for a request or command. Preserve the imperative and do not make it a report of an action already taken.

Record both possibilities when needed, identify what additional context would decide between them, and never present a plausible guess as though the original made it explicit.

3. -아/어서 plus let’s-suggestion

generally unsuitable in the straightforward causal use. Check whether a different connective is needed for a proposed joint action.

Record both possibilities when needed, identify what additional context would decide between them, and never present a plausible guess as though the original made it explicit.

4. -(으)니까 plus let’s-suggestion

natural for a reason motivating a joint action. The target should express ‘since…, let’s…’ instead of merely a past explanation.

Record both possibilities when needed, identify what additional context would decide between them, and never present a plausible guess as though the original made it explicit.

5. -아/어서 as sequence

can link an action to what follows in temporal order. Ask whether because, then, or a natural English infinitive is most faithful.

7. past events

source tense normally appears on the final predicate in elementary causal -아/어서 patterns. Locate the temporal reference of the whole clause pair.

8. two English because sentences

the same English surface may represent different Korean discourse purposes. Use speaker intention and final-clause type to choose the natural Korean rendering.

A repeatable twelve-step translation method

Step 1: Read the whole utterance before the disputed form

A sentence fragment can hide whether the speaker is reporting a fact, proposing an action, or identifying a quantity. Reading complete context prevents a fluent but false translation.

Apply this to Korean 아서 versus 니까 translation by using a two-column note: left, what the source form actually says or implies; right, the English words needed to make that same meaning recoverable. If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 2: Identify the clause or noun-phrase boundary

Mark boundaries before rearranging word order. If an English draft joins the wrong words, even a perfect dictionary entry will not rescue the relationship.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 3: Name the event, entity or speech act

Ask what action is occurring and who is affected, or what item is being counted. The answer should be a real description of the scene, not a list of grammar labels.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 4: Write the literal structural gloss privately

A structural gloss is a temporary diagnostic tool. It reveals the function of a form, but it is not the finished translation that a reader should be forced to decode.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 5: Mark what the source commits to as fact

Separate assertions from wishes, hypotheticals, instructions and general statements. Translation fails most seriously when a reader is told that something happened which the original only suggested.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 6: Record the contrast the grammar contributes

If two source forms contrast, preserve that distinction in English as far as context allows. Do not invent a difference where both source expressions work naturally.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 7: Check surrounding time, actors and context

Check whether the speaker is addressing a person, describing a habit, locating events in a sequence or pointing to a particular item. The right English often depends on that reference.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 8: Draft a clear English meaning-first rendering

Make the first draft fully intelligible to an English reader. Plain wording is preferable to a technically literal sentence whose grammar changes the source’s social or factual meaning.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 9: Draft a second valid English wording

A second draft exposes overconfidence. It tests whether the first solution was uniquely justified or merely one natural option within a legitimate range.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 10: Test the two against the source

A translation earns its place by recovering the same event structure, commitment and reference. Compare the original and both drafts; do not choose purely because one English sentence sounds fashionable.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 11: Check what the translation adds or omits

Look for changed quantities, missing negatives, added certainty, switched participants and false chronology. These are meaning errors even when all the individual words look familiar.

If the English side requires an extra assumption, annotate it rather than silently introducing it. The method is deliberately slow during practice so that the underlying decision becomes quicker and more reliable in live reading.

Step 12: Read aloud, reverse-test and finalise

Read the result as a natural message, then reconstruct the source situation from English alone. If that reconstruction differs from the original, revise before publishing.

Twenty-four fully worked translation examples

Worked example 1: 비가 와서 집에 있었어요.

Source: 비가 와서 집에 있었어요.
Natural English: It rained, so I stayed home.

Meaning decision: The first clause supplies a weather cause and the second reports the consequence. The source expression should be read as a complete relationship, not as a puzzle in which every visible syllable must be represented by a distinct English word. The draft above is designed for ordinary English comprehension; a word-for-word gloss would be useful only as private analysis. In context, decide whether the translated statement reports an event, frames a possibility, gives advice, or identifies an exact unit of quantity.

Failure to watch for: The sentence is not ordering the listener to stay home. This is not merely a style issue. A reader may reconstruct a different timeline, social action or object count from an English sentence that looks superficially grammatical. To test the draft, cover the source, read the English aloud and state what it commits the speaker to. Now uncover the source and compare those commitments one by one. If they differ, correct the relationship first; only then improve the sentence’s rhythm.

Transfer exercise: Change one element of this example—time, speaker, addressee, quantity, or the event that follows—and explain whether the same English wording still works. The correct habit is to notice when the meaning boundary moves. Some variants will allow several natural English phrasings; that is acceptable if each one preserves the information the source actually supplies. This is how worked examples become a usable translation skill rather than memorised answers.

Worked example 2: 늦어서 죄송합니다.

Source: 늦어서 죄송합니다.

To test the draft, cover the source, read the English aloud and state what it commits the speaker to. Now uncover the source and compare those commitments one by one. If they differ, correct the relationship first; only then improve the sentence’s rhythm.

Transfer exercise: Change one element of this example—time, speaker, addressee, quantity, or the event that follows—and explain whether the same English wording still works. The correct habit is to notice when the meaning boundary moves. Some variants will allow several natural English phrasings; that is acceptable if each one preserves the information the source actually supplies. This is how worked examples become a usable translation skill rather than memorised answers.

Worked example 13: 숙제를 해서 피곤해요.

Source: 숙제를 해서 피곤해요.
Natural English: I’m tired because I did my homework.

Meaning decision: The previous activity explains a current feeling.

Twelve failure modes and how to repair them

Failure 1: Treating -아/어서 and -(으)니까 as interchangeable because both can be glossed because.

Diagnosis: Treating -아/어서 and -(으)니까 as interchangeable because both can be glossed because. Start the repair by locating the smallest unit where meaning changed, not by rewriting the entire English paragraph. Compare the source relationship with the English reader’s likely interpretation. If the fault is a changed event boundary, quantity, modality or speaker intention, revise that part explicitly and rerun the reverse test.

Recovery practice: choose a worked example above that could trigger this error, explain the false reading in one sentence, then produce a corrected translation. Repeat the same test with a new noun or verb so the rule survives outside a memorised expression. A convincing correction says why the old version was wrong rather than simply supplying a replacement.

Failure 2: Failing to inspect whether the second clause is an instruction.

Diagnosis: Failing to inspect whether the second clause is an instruction. Start the repair by locating the smallest unit where meaning changed, not by rewriting the entire English paragraph.

Guided translation practice with explained answers

Practice 1: Translate 비가 와서 집에 있었어요.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: It rained, so I stayed home.

Reasoning: The first clause supplies a weather cause and the second reports the consequence. The main error to prevent is this: The sentence is not ordering the listener to stay home. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 2: Translate 늦어서 죄송합니다.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: I am sorry for being late.

Reasoning: The causal relation is part of a conventional apology. The main error to prevent is this: A literal ‘Because I am late, I am sorry’ is understandable but stiff. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 3: Translate 배고파서 밥을 먹었어요.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: I ate because I was hungry.

Reasoning: The first state explains an already completed action. The main error to prevent is this: Do not mistake the sentence for an invitation to eat. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 4: Translate 시간이 없으니까 서두르세요.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: We have little time, so please hurry.

Reasoning: A reason supports an imperative directed at the listener. The main error to prevent is this: The -세요 ending asks for action, it is not a description of hurrying. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 5: Translate 추우니까 창문을 닫으세요.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: It’s cold, so please close the window.

Reasoning: The cold weather justifies the requested action. The main error to prevent is this: Using -아서 for the same straightforward command is not the normal learner pattern. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 6: Translate 배가 아파서 학교에 못 갔어요.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: I couldn’t go to school because my stomach hurt.

Reasoning: The pain explains inability to attend school. The main error to prevent is this: Do not convert 못 갔어요 into a voluntary choice not to go. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 7: Translate 날씨가 좋으니까 산책합시다.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: The weather is nice, so let’s take a walk.

Reasoning: The reason motivates a shared proposal. The main error to prevent is this: The final -합시다 is a suggestion, not a reported stroll. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 8: Translate 돈이 없어서 못 샀어요.

Suggested answer: I couldn’t buy it because I had no money.

Reasoning: The financial circumstance explains a completed failure to buy. The main error to prevent is this: Retain inability rather than claiming the speaker refused to purchase. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 9: Translate 바쁘니까 내일 만나요.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: I’m busy, so let’s meet tomorrow.

Reasoning: The speaker uses being busy as a reason for a scheduling proposal. The main error to prevent is this: In context 만나요 can also be a plan; the speech act matters. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 10: Translate 길이 막혀서 늦었어요.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: I was late because of the traffic.

Reasoning: The traffic caused a delay; no instruction is present. The main error to prevent is this: Do not interpret 막히다 as literal blockage of a door. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 11: Translate 졸리니까 일찍 자세요.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: You’re sleepy, so go to bed early.

Reasoning: An observed or inferred state supports advice. The main error to prevent is this: Do not change the advice into a statement that someone already slept. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty.

Suggested answer: I was glad to see my friend.

Reasoning: The connection is close enough that English normally prefers an infinitive. The main error to prevent is this: A clumsy repeated ‘because’ is not required. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 13: Translate 숙제를 해서 피곤해요.

Reasoning: The previous activity explains a current feeling. The main error to prevent is this: Do not imply that the source orders homework to be done. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 14: Translate 숙제를 다 했으니까 쉬어도 돼요.

Attempt the sentence without looking at the worked section. First mark the significant grammar, then write natural English. Before checking, decide what could be lost if you translated each component word for word. Record any uncertainty instead of filling it with an invented fact.

Suggested answer: You’ve finished your homework, so you can rest.

Reasoning: A completed task is grounds for granting permission. The main error to prevent is this: The conclusion is permission, not a command to rest. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Suggested answer: I rested because I was tired.

Reasoning: A reported cause precedes a reported action. The main error to prevent is this: The verb 쉬었어요 is past; do not invent a present recommendation. Alternatives are acceptable when they preserve the same information, speech act and degree of certainty. In self-assessment, award yourself separate marks for factual accuracy, grammatical relationship, natural English and ability to explain the contrast.

Practice 17: Translate 피곤하니까 좀 쉬세요.

Transfer: how to use this skill outside exercises

1. A short conversation

Write a six-line conversation in the source language, underline every relevant form, and translate it twice: once as a close gloss and once as natural English. Explain which details must survive the change of wording.

For Korean in particular, use the main question of this guide—distinguish a Korean causal link describing an event from a reason supporting a decision, request, suggestion or instruction—as the marking criterion. A fluent sentence is not sufficient if it loses the governing contrast. Make one deliberately wrong version, identify what a reader would infer from it, then restore the correct meaning. This second pass makes the source’s hidden grammar visible and helps prevent future drift.

2. A practical message

Translate a message that would plausibly be sent to a colleague, customer or classmate. Check whether the English adds a promise, changes a request, loses a count, or alters who should act.

For Korean in particular, use the main question of this guide—distinguish a Korean causal link describing an event from a reason supporting a decision, request, suggestion or instruction—as the marking criterion. A fluent sentence is not sufficient if it loses the governing contrast. Make one deliberately wrong version, identify what a reader would infer from it, then restore the correct meaning. This second pass makes the source’s hidden grammar visible and helps prevent future drift.

3. A short narrative

Choose four connected sentences. Draw a time line, label the speaker’s intention and identify which words carry the distinction under study. Translate the paragraph, then reconstruct its events from English alone.

For Korean in particular, use the main question of this guide—distinguish a Korean causal link describing an event from a reason supporting a decision, request, suggestion or instruction—as the marking criterion. A fluent sentence is not sufficient if it loses the governing contrast. Make one deliberately wrong version, identify what a reader would infer from it, then restore the correct meaning. This second pass makes the source’s hidden grammar visible and helps prevent future drift.

4. A paired comparison

Take two similar source sentences that differ only in the key grammar. Produce English versions that preserve the difference. If both English sentences happen to be identical, explain why the source distinction is not essential in that particular context.

For Korean in particular, use the main question of this guide—distinguish a Korean causal link describing an event from a reason supporting a decision, request, suggestion or instruction—as the marking criterion. A fluent sentence is not sufficient if it loses the governing contrast. Make one deliberately wrong version, identify what a reader would infer from it, then restore the correct meaning. This second pass makes the source’s hidden grammar visible and helps prevent future drift.

5. A real editing pass

Ask a second reader to identify the people, actions, times and quantities from your English text without seeing the source. Treat disagreement as a reason to investigate rather than automatically blaming the reader.

For Korean in particular, use the main question of this guide—distinguish a Korean causal link describing an event from a reason supporting a decision, request, suggestion or instruction—as the marking criterion. A fluent sentence is not sufficient if it loses the governing contrast. Make one deliberately wrong version, identify what a reader would infer from it, then restore the correct meaning. This second pass makes the source’s hidden grammar visible and helps prevent future drift.

6. A delayed return

Leave the examples for a day. Redo six without prompts, mark your first decision and explain two errors. The best evidence of progress is independent transfer to a sentence that you did not rehearse.

Frequently asked questions

Do both Korean forms mean because?

Often, but they do not do the same discourse job in every sentence. Translation is a decision about cause, justification and the kind of second clause.

A useful follow-up is to test that answer with two of the worked examples above: one straightforward and one that might be misread. Say what changes, what stays invariant, and what context you would need if the evidence were incomplete. This turns a definition into a reliable translation decision.

Why is -(으)니까 common before commands?

It can present a reason for the speaker’s request or instruction. In many standard learner constructions -아/어서 is not used in that same direct-command position.

Can -아/어서 mean and then?

Yes. Some uses are sequential. Context, verb meanings and the second event decide whether because, then or another natural English structure is best.

A useful follow-up is to test that answer with two of the worked examples above: one straightforward and one that might be misread. Say what changes, what stays invariant, and what context you would need if the evidence were incomplete. This turns a definition into a reliable translation decision.

Can I translate -(으)니까 as since?

Yes when English since clearly presents a reason. Avoid since if readers may confuse it with a temporal starting point.

Does -세요 automatically require -(으)니까?

No. A stand-alone -세요 imperative needs no causal connector. The distinction applies when a preceding clause provides a reason for that imperative.

Are apologies an exception?

Common apologies such as 늦어서 죄송합니다 conventionally use -아서. Treat the whole expression as an apology rather than as a generic statement plus arbitrary conjunction.

A useful follow-up is to test that answer with two of the worked examples above: one straightforward and one that might be misread. Say what changes, what stays invariant, and what context you would need if the evidence were incomplete. This turns a definition into a reliable translation decision.

Does Korean mark past time in the first clause?

Ordinary learner patterns with -아/어서 commonly put tense information in the final clause. Do not insert extra past markers by imitating English word order.

A useful follow-up is to test that answer with two of the worked examples above: one straightforward and one that might be misread. Say what changes, what stays invariant, and what context you would need if the evidence were incomplete. This turns a definition into a reliable translation decision.

What if the sentence ends as a question?

Ask whether it is a neutral enquiry, an explanation-seeking question or a disguised request. A punctuation mark alone cannot determine the whole connective choice.

A useful follow-up is to test that answer with two of the worked examples above: one straightforward and one that might be misread. Say what changes, what stays invariant, and what context you would need if the evidence were incomplete. This turns a definition into a reliable translation decision.

How do I teach this to beginners?

Contrast ‘I stayed in because it rained’ with ‘It’s raining, so take an umbrella’. Both use a reason, but only the second directs the listener.

Does Korean because translate word for word?

No. English may prefer ‘so’, ‘since’, an infinitive, or two sentences. Preserve the relation, not the number of conjunction words.

Can I rely on machine translation?

Use it as a proposal. Check commands, joint suggestions and apology formulae manually, because a fluent output can hide a changed speech act.

How do I correct my own sentences?

Write the second clause first, label it statement, request or suggestion, then select the Korean connector and read both clauses aloud as one utterance.

A practical accuracy checklist

• Did I preserve the event and its participants?
• Did I preserve whether this is a fact, a suggestion, a request, a habit or an imagined alternative?
• Did I retain negation, number, time, and any measure unit?
• Is the word order natural in English?
• Could a reader infer something the source never asserted?
• Can I explain the choice without relying on a memorised one-word rule?

What mastery looks like

You have learned Korean translation well when you can read a fresh sentence, identify the decisive grammatical contrast, translate it naturally, defend your choice and explain why a tempting alternative would change the meaning. The objective is not to preserve every surface word. It is to preserve the structure of the event and the choices the speaker actually made, so a reader in another language can act on the same information.
