Temporal connectives in translation tell readers how events, states and time intervals relate: what happened before or after something else, what overlapped, what continued until a boundary, what began at a starting point, and what occurred as soon as another event was complete. Words such as before, after, while, until, since, once, when, whenever, as soon as and by the time may look small, but they can control the entire timeline of a sentence. A fluent translation that reverses one temporal relation can reverse causality, procedure, responsibility or chronology.
People searching for how to translate before and after, while, until, since, once, when, whenever, as soon as, by the time, temporal clauses, event order or sequence markers are solving an inter-event relation problem. Languages differ in tense systems, aspect, clause order, temporal particles and whether future time clauses use future morphology. The source connective may also be ambiguous: since can mean a starting time or a reason; while can mark simultaneous events or contrast; as can express time, cause or manner. Precise translation therefore starts with a timeline, not a dictionary.
This article owns the temporal-connective and event-order precision layer in eduKateSG’s translation architecture. It focuses on relations between events and intervals rather than on tense morphology itself. It covers precedence, succession, overlap, duration, boundaries, starting points, deadlines, recurrence, immediate sequence, nested timelines and temporal ambiguity. It routes verb tense to the existing Tense, Aspect and Time owner and event-internal boundaries to Lexical Aspect and Telicity. Its governing rule is straightforward: place the source events on a timeline before selecting the target connective.
1. Temporal Meaning Has More Than One Layer
A sentence can encode time through verb tense, grammatical aspect, lexical event type, adverbs, dates and relations between clauses. She had left before he arrived uses tense plus the connective before. She left at 8:00 uses a clock-time expression. She kept working until midnight combines an ongoing event with a boundary.
This article concentrates on the relational layer: EVENT A relative to EVENT B. That distinction prevents unnecessary collision with broader tense work. A target language may preserve event order with very different verb forms. If A is still before B, the relation can be accurate even when the surface tense pattern changes.
2. Build the Timeline Before You Translate
For difficult sentences, write each event on a separate line: A = alarm sounded; B = staff evacuated; C = fire service arrived. Then add relations: A BEFORE B; B BEFORE C. If two events overlap, mark A OVERLAPS B. If one continues up to a boundary, mark A UNTIL B.
This method is deliberately simple. It converts grammatical complexity into a visual order that can be compared across languages. After translation, rebuild the timeline from the target alone. If the event order changes, the translation has changed meaning regardless of how natural the sentence sounds.
3. Before: A Precedes B
A happened before B means A is earlier on the relevant timeline. Check the seal before opening the container requires checking first and opening later. In procedures, that order may be safety-critical.
Languages may express precedence through a connective, participial construction, case-marked nominal, serial verb or simple ordered clauses. The target need not copy English syntax. It must make the operational sequence clear: CHECK → OPEN. A procedure that becomes OPEN → CHECK is not stylistically different; it is wrong.
4. After: B Precedes A
A happened after B means B occurred first. Restart the system after the update finishes establishes FINISH UPDATE → RESTART. The grammatical order places restart before update in the sentence, while chronological order is the opposite.
This is an important diagnostic lesson: sentence order does not equal event order. Translators who follow linear word sequence can accidentally reverse instructions. Always translate the relation, not the textual position. A simple arrow diagram protects against this error.
5. Before Does Not Always Entail That the Later Event Happened
She left before I could speak normally implies that her departure prevented or pre-empted the speaking event. The second event may never have occurred. Similarly, The company closed before the investigation could finish does not entail that the investigation later finished.
This is a subtle but important difference between temporal ordering and event actuality. Before-clauses can describe a potential event used as a boundary rather than a completed event. The translator should check whether EVENT B is asserted, presupposed, expected or merely counterfactual/potential. Do not create a completed event where the source leaves it unrealized.
6. After Usually Carries Stronger Event Actuality
She called after the meeting ended normally presents the meeting’s ending as an actual event and places the call later. This differs from certain before-constructions where the later boundary event may not occur.
Target languages can encode this asymmetry differently. The translator should not assume that before and after are perfect mirror images in every context. Ask whether both events are asserted to have occurred. Event actuality belongs in the timeline map beside ordering.
7. While: Temporal Overlap
Temporal while places two events or states in overlapping intervals. While Lina prepared the slides, Omar checked the figures. The sentence does not require both activities to begin or end at exactly the same moment. It says their relevant intervals overlap.
The target may use a simultaneous-action marker, subordinate clause, participle or simple coordination depending on the language. Preserve overlap rather than forcing exact simultaneity. A good timeline draws two horizontal bars with an intersecting section rather than two single points.
8. While Can Also Mean Contrast
Lina prefers tea, while Omar prefers coffee often has no temporal meaning. It contrasts two preferences. A literal temporal translation could suggest that the preferences exist only simultaneously or during a particular interval.
When the source connective is while, test both readings: at the same time as versus whereas/in contrast. The new Discourse Relations and Connectives article owns the contrastive reading; this article owns temporal overlap. Context decides which architecture applies.
9. During Is Not the Same as While
English during normally introduces a noun phrase: during the meeting. While normally introduces a clause: while the meeting was in progress. Both can locate an event inside an interval, but their grammar differs.
Other languages may use one form for both or require different structures. Translate the temporal containment relation first: the smaller event occurs within the larger interval. Then select a target construction appropriate to whether the source packages the interval as a noun, event or clause.
10. Until: Continuation Up to a Boundary
She worked until midnight presents work as continuing up to a temporal boundary. The sentence does not necessarily describe what happened after midnight, though ordinary interpretation often suggests the work stopped then.
The key semantic structure is STATE/ACTIVITY CONTINUES → BOUNDARY. Translators should preserve both continuation and endpoint. A target equivalent meaning merely before midnight is weaker because the work could have occurred briefly at any earlier point. Until creates continuity toward the boundary.
11. Not Until: A Boundary for First Occurrence
The server did not restart until 03:00 normally means there was no restart before 03:00 and the restart occurred at that boundary or after it in the relevant interpretation. The negative does not simply deny restarting.
Map the interval explicitly: before 03:00 = NOT restart; boundary = restart becomes possible or actual. This construction sits at the intersection of time and negation. Use the new Negation and Scope article when the target risks moving the negative away from the temporal boundary.
12. By Is a Deadline, Not a Duration
Submit the form by Friday sets Friday as the latest permitted completion point. Submission may happen earlier. Work until Friday instead describes continuation up to Friday. Confusing by and until changes a deadline into a duration.
Operationally, draw a window. BY Friday = any acceptable completion time at or before the deadline. UNTIL Friday = activity continues through the preceding interval toward the boundary. In contracts, applications, examinations and project schedules, this distinction can determine compliance.
13. By the Time Links a Deadline-Like Boundary to Another Event
By the time the auditor arrived, the files had been copied places copying before or no later than the auditor’s arrival. The arrival acts as a reference boundary. English often combines this with perfect aspect, but the temporal relation is more fundamental than the specific verb form.
A target language may express the relation through clause order or aspect markers rather than an equivalent phrase. Verification question: at the moment the auditor arrived, was copying already complete? If the target permits copying to begin only after arrival, the relation has reversed.
14. Since: Starting Point in Time
Temporal since identifies a starting point or starting event from which a state or repeated activity extends toward a reference time. She has lived there since 2022 places the beginning in 2022 and continuity toward the present. Much has changed since the school reopened uses an event as the starting boundary.
The target language may not use English present perfect. That is acceptable if the start point and continuation relation remain intact. Write START = 2022; STATE = living there; REFERENCE = now. This relational map is more reliable than copying tense morphology.
15. Since Can Also Mean Because
Since the road is closed, we will take another route is normally causal, not temporal. No starting interval is required. A translator who chooses a temporal equivalent can produce nonsense or a misleading chronology.
Test whether since can be replaced by because without changing the intended relation. If yes, use the discourse-causal analysis. If it can be replaced by from the time that, use temporal analysis. The same English word can therefore route to two different translation owners.
16. For and Since Answer Different Temporal Questions
Since 2022 identifies a starting point. For four years identifies a duration. They can describe the same real-world interval when the reference time makes the arithmetic work, but they conceptualize it differently.
Do not translate both with a generic time expression if the distinction matters. In records, eligibility rules or experience requirements, for three years may be a minimum duration while since 2023 fixes a calendar start. Preserve whether the source specifies boundary or length.
17. When: A Flexible Temporal Anchor
When can link an event to a time point, repeated situation or larger interval. When the alarm sounded, everyone left. When I was a child, we lived near the sea. When the light turns green, press Start. These uses share temporal anchoring but differ in event type and recurrence.
The target language may require more specific choices. Identify whether the source refers to a single occurrence, a habitual relation, a state interval or a future trigger. The connective’s job is not simply “time”; it defines which temporal relation activates the main clause.
18. When Can Also Be Close to If
In instructions, When the indicator turns green, press Start often presupposes or expects that the indicator will turn green. If the indicator turns green presents the event more conditionally. The two may lead to the same action in practice, but their assumptions differ.
Do not replace temporal when with conditional if merely because the target language permits it. Ask whether the source treats the event as expected, recurrent or uncertain. For formal condition logic, route to Conditions and Exceptions.
19. Whenever: Repeated Temporal Trigger
Whenever the pressure rises above the limit, the valve opens describes a recurring relation across relevant occasions. It is not simply one historical event. The connective combines temporal recurrence with a generalized condition-like pattern.
Translate the recurrence. A target equivalent of simple when may be sufficient in a language where context supplies habitual meaning, but verify that the sentence still applies on every relevant occurrence rather than one episode. Frequency and generality are part of the instruction.
20. Once: Completion or Threshold Before the Next Event
Temporal once often means when X has happened or become true, then Y. Once the seal is broken, the warranty is void establishes a threshold. Once the file has uploaded, close the window requires upload completion before closing.
Do not confuse temporal once with frequency once meaning one time. The target may use unrelated forms. Diagnostic: can the source be paraphrased as after X reaches completion/state, Y? If yes, preserve the threshold relation.
21. As Soon As: Minimal Delay After a Trigger
Call me as soon as you arrive means the call should follow arrival with minimal relevant delay. It is stronger than ordinary after you arrive, which only establishes order.
In emergency instructions, service commitments and workflow handoffs, losing immediacy matters. The target should preserve both sequence and urgency. If no exact connective exists, a natural expression meaning immediately after may be more precise than a generic after-marker.
22. Immediately Before and Immediately After
Adding immediately narrows the acceptable gap between events. Record the reading immediately before shutdown differs from record the reading before shutdown, which permits a much earlier measurement.
Translate adjacency in time when it matters. A target that preserves only precedence but removes minimal separation can invalidate a scientific procedure or operational log. Time relations have both order and distance; some connectives specify both.
23. As: Time, Cause, Manner or Role?
English as is highly polysemous. As the train approached, the lights flashed can be temporal. As the road was closed, we turned back can be causal. Do as I showed you expresses manner. She works as an engineer marks role.
A translator should never choose the target equivalent until the relation is classified. Replace as with a diagnostic paraphrase: while/when, because, in the way that, or in the role of. The correct paraphrase reveals which translation system should handle the sentence.
24. Meanwhile: Parallel Timeline Management
Meanwhile tells readers that another event or storyline occupies an overlapping or nearby interval, often shifting attention to a different participant or place. In narratives, reports and incident timelines, it helps readers manage parallel developments.
A target equivalent of plain then can incorrectly serialize events that were simultaneous. Conversely, using a simultaneity marker where the source simply moves to the next event can create overlap. Ask whether the narrative camera is switching to something happening during the same period.
25. Then: Sequence, Consequence or Discourse Step
Then can mark chronological succession: She saved the file, then closed the program. It can also participate in condition-result structures: If the test fails, then repeat Step 2. In conversation, it can mark a discourse transition rather than exact time.
Translate according to function. A language may omit an explicit equivalent in conditionals while preserving the logic. In narratives, however, deleting a sequence marker may blur chronology. Build the event relation first, then decide whether the target needs a visible marker.
26. Next, Afterwards, Subsequently and Later
Sequence adverbials differ in precision and register. Next often identifies the following step. Afterwards indicates later time without necessarily saying how much later. Subsequently is formal and common in reports. Later can refer to a more distant or unspecified point.
Do not use these as interchangeable stylistic decorations. In instructions, next may establish immediate workflow order. In historical prose, subsequently may signal only later chronology, not causation. A target connective should preserve both temporal relation and rhetorical register.
27. Earlier, Previously, Formerly and Already
Backward-looking temporal expressions also differ. Earlier locates an event before a reference point. Previously often refers to an earlier state or occurrence in a formal register. Formerly can indicate a previous role or name no longer current. Already often signals that an event has occurred by a reference point, sometimes sooner than expected.
Translation should preserve temporal orientation plus any expectation. The train has already left is not identical to The train left earlier. The first can imply that departure has happened by now, possibly earlier than someone expected. Small adverbs can carry both chronology and stance.
28. Still, Yet and No Longer Encode Changing States
Still active means a state continues. Not yet active says the state has not begun by the reference time but may begin later. No longer active says the state held before and has ended. These expressions locate the present relative to state boundaries.
The new Negation and Scope owner handles the negative logic; temporal analysis adds BEFORE / NOW / AFTER. This is particularly important in eligibility, licences, subscriptions and system status, where a target equivalent of generic inactive can erase whether activation is pending or has ceased.
29. From … To and From … Until
Range constructions identify interval boundaries. Open from 09:00 to 17:00 describes an operating interval. From Monday until Friday establishes a start and endpoint. Whether the endpoint is inclusive can depend on convention and context.
For schedules and legal periods, do not assume inclusivity. If the source provides dates and times, preserve them exactly and inspect domain conventions. A translation can be grammatically flawless yet create a one-day or one-hour error by implying the wrong endpoint interpretation.
30. No Earlier Than and No Later Than
No earlier than 10:00 sets a minimum time: the event must occur at 10:00 or later. No later than 10:00 sets a maximum time: the event must occur at 10:00 or earlier. These phrases combine temporal comparison with negation.
Convert them into inequalities before translating. NO EARLIER THAN 10:00 = time ≥ 10:00. NO LATER THAN 10:00 = time ≤ 10:00. This simple mathematical check prevents a surprisingly common reversal. For numeric comparison more broadly, use the existing Quantifiers and Comparisons owner.
31. Event Order Is Not Necessarily Causal Order
The alarm sounded, and then the lights went out establishes sequence but does not necessarily say the alarm caused the outage. Humans often infer causation from temporal succession, but translation should not strengthen that inference without evidence.
This is where the temporal layer meets discourse relations. A target equivalent of therefore would add causal or inferential force. Preserve chronology as chronology unless the source explicitly or contextually establishes causation. Post hoc sequence is not automatically cause.
32. Sentence Order Is Not Necessarily Event Order
After checking the lock, Lina left mentions checking before leaving and also places checking first chronologically. Before Lina left, she checked the lock likewise aligns clause and event order differently from many other constructions. But Lina left after checking the lock mentions leaving first while it occurred second.
Never infer chronology from the order of clauses alone. Parse the connective. Languages with flexible clause ordering can rearrange information for topic and focus while keeping the same timeline. The target may reorder clauses naturally as long as the temporal relation survives.
33. Future Time Clauses Do Not Use Future Forms the Same Way Across Languages
English commonly says When she arrives, we will begin, not ordinarily when she will arrive in this temporal-clause meaning. Other languages may use future marking in both clauses, a special subordinate mood, or no tense equivalent at all.
Do not force English tense restrictions onto the target, and do not import target future morphology mechanically into English. Preserve the temporal dependency: arrival precedes or triggers beginning. The surface tense system is language-specific. For the broader grammatical layer, route to How to Translate Easily | Tense, Aspect and Time.
34. Aspect Changes How Temporal Connectives Are Interpreted
When I arrived, she cooked and When I arrived, she was cooking do not present the same event structure. In the second, cooking is already in progress around the arrival point. In the first, depending on context and dialect, cooking may be interpreted as a bounded event associated with arrival.
Temporal connectives therefore interact with viewpoint aspect. Use the existing tense/aspect owner for grammatical perspective and Lexical Aspect and Telicity for event-internal shape. This article asks how those events are positioned relative to each other.
35. Completion Matters in Once, After and As Soon As
After reading the report, sign the form commonly implies that the reading event reaches an appropriate completion before signing. Once the upload completes, close the window makes completion explicit. As soon as the upload starts, close the window uses a different boundary.
Mark which event boundary activates the next action: START, DURING or COMPLETE. Translators often preserve event names but move the trigger from completion to initiation. In procedures, that can break the process even though the sentence remains easy to read.
36. Nested Timelines Need More Than Two Events
Long sentences may contain several temporal layers: After the team finished testing, but before the client arrived, the engineer copied the logs that had been generated while the system was running. A simple before/after pair is no longer enough.
Build a timeline graph: system running overlaps log generation; testing finishes; log copying occurs after testing but before client arrival. Then translate. If a target language prefers splitting the sentence, do so. Sentence count may change; chronology must not.
37. Temporal Connectives in Procedures
Instructions are especially sensitive because temporal relations determine action order. Disconnect power before removing the cover, wait until the indicator stops flashing, restart after the update completes and record the reading while the pump is running each define a different operational relationship.
Verification should simulate the procedure. Imagine a person following the target literally. Do they disconnect before opening? Do they wait through the entire flashing interval? Do they take the measurement during pump operation? If target behaviour differs, the temporal translation is wrong.
38. Temporal Connectives in Legal Deadlines and Eligibility
Legal and administrative text distinguishes before, by, no later than, within, after, from, until and during because each defines a different compliance window. Within 14 days after receipt creates a duration measured from an event. By 14 June creates a calendar deadline.
Do not convert relative periods into absolute dates unless the source or workflow authorizes calculation, and do not assume whether the starting day counts without domain guidance. Preserve the wording precisely and flag ambiguity where stakes are high. Temporal translation can become legal interpretation if the translator silently resolves a disputed counting rule.
39. Temporal Connectives in Incident Logs
Incident reports depend on chronology. The alarm sounded before the pressure dropped points investigators toward a different sequence from after the pressure dropped. While the operator restarted the pump, the sensor continued to report an error indicates overlap.
Preserve source timestamps separately from narrative connectives, then compare them. If a connective contradicts recorded times, do not silently repair the source unless the task explicitly includes factual editing. Translation should represent the source accurately while allowing an editor or investigator to resolve the inconsistency.
40. Temporal Connectives in History and Narrative
Historical and literary writing uses time relations not only to order events but to control perspective. A narrator may flash back with years earlier, foreshadow with later, hold two scenes together with meanwhile, or compress years into one transitional phrase.
Over-explicit translation can flatten narrative timing. Under-explicit translation can make readers lose track of chronology. Preserve the author’s temporal distance and pacing as well as raw order. A literary timeline has informational and stylistic dimensions.
41. Worked Example: Submit by Friday vs Work Until Friday
Source A: Submit the assignment by Friday. Acceptable submission can occur before Friday; Friday is the deadline. Source B: Work on the assignment until Friday. The work is presented as continuing toward Friday. The same time noun appears, but the interval logic differs.
Diagnostic map for A: completion time ≤ Friday deadline. Diagnostic map for B: activity extends through the preceding interval toward Friday boundary. A target that uses one generic preposition for both may need supporting wording to preserve the distinction.
42. Worked Example: She Left Before I Could Reply
EVENT A = she left. EVENT B = I reply. Relation = A precedes the opportunity/completion of B. Importantly, B is not asserted to have occurred. The sentence often implies that departure prevented the reply.
A target equivalent of She left, and then I replied creates an actual reply and changes the narrative. Verification must therefore record EVENT STATUS as well as order: A actual; B unrealized or not achieved before A.
43. Worked Example: While the Pump Was Running
Source: Record the temperature while the pump is running. EVENT A = record temperature; INTERVAL B = pump running. Relation = A occurs inside/overlaps B. The instruction does not say to wait until the pump stops.
Operational verification: if a user following the target records the temperature after shutdown, the translation has failed. This example shows why temporal connectors in procedures should be tested through action, not only through grammar.
44. Worked Example: Since the Office Reopened
Source: Customer visits have increased since the office reopened. The natural reading is temporal: reopening establishes the start boundary for the period in which increase is observed. It does not necessarily claim that reopening caused the increase.
A target causal marker equivalent to because would add causation. Diagnostic paraphrase: from the time the office reopened until the reference time. If that paraphrase fits, preserve temporal since.
45. Worked Example: Once the Seal Is Broken
Source: Once the seal is broken, the product must be used within 24 hours. EVENT A = seal becomes broken. EVENT B = 24-hour usage window begins. The connective establishes a threshold that activates a new timing rule.
The target must not start the 24-hour window before the seal breaks or only after some later event. Draw the trigger explicitly. For products, warranties, laboratory procedures and compliance rules, threshold timing is part of the requirement.
46. The EVENT-TIME Diagnostic
Use eight fields for difficult temporal passages: EVENT A / EVENT B / ORDER / OVERLAP / BOUNDARY / DURATION / ACTUALITY / REFERENCE TIME. ORDER records before/after. OVERLAP records simultaneity. BOUNDARY records start, end or threshold. DURATION records length where relevant. ACTUALITY records whether each event really occurred or is potential. REFERENCE TIME identifies now, a past report time or another anchor.
After translation, reconstruct those fields from the target. If the target matches on words but differs on one field, revise. This diagnostic is especially strong for long sentences because it separates several temporal meanings that grammar may bundle together.
47. Verification by Timeline Drawing
A timeline does not need specialist notation. Points work for short events; horizontal bars work for states and activities; arrows show sequence; brackets show intervals. Mark deadlines and thresholds vertically. Then draw the target interpretation separately.
If the diagrams differ, the translation differs. This is one of the rare QA techniques that works even when the reviewer does not want to debate grammatical terminology. It turns a linguistic disagreement into a concrete question: which event happens first, which continues, and what has happened by the boundary?
48. Verification by Calendar Substitution
Replace vague temporal expressions with concrete dates or times. If the source says within three days after Monday, imagine actual calendar points. If it says before noon, test 11:59 and 12:01. Concrete substitution exposes reversed boundaries and misunderstood deadlines.
Do not use this technique to invent official deadline calculations where legal counting rules are unknown. Use it as a semantic test. The purpose is to see what the linguistic form permits, not to make an unauthorized legal determination.
49. Recovery When Event Order Has Reversed
When a target reverses chronology, remove all tense and connective wording temporarily. Write the event labels and source arrows. Then rebuild the target around those arrows. Do not patch only the connective if tense or aspect has also adapted to the wrong order.
After repair, check causal and procedural consequences. A reversed temporal order may have changed who could know what, which condition had been satisfied, or whether an action was permitted. Timeline recovery should therefore trigger a local reread of surrounding sentences.
50. Recovery When Overlap Has Become Sequence
If while or an equivalent simultaneous construction becomes a simple next-step marker, restore the overlapping intervals first. Decide whether one event contains the other or whether they merely intersect. Then choose target aspect and connective accordingly.
This matters in witness accounts and operational logs. The alarm sounded while the operator was restarting the pump can indicate that the restart was already in progress. A target saying the alarm sounded and then the operator restarted the pump creates a different sequence and potentially a different explanation of the incident.
51. Recovery When a Deadline Becomes a Duration
Errors between by, until, within and for often survive proofreading because the target still contains the correct date or number. Repair requires classifying the time expression: DEADLINE, END BOUNDARY, WINDOW, or DURATION.
Once classified, rebuild the target with the domain’s normal expression. Verify using example times. If a source permits completion two days early but the target requires activity to continue until the deadline, the semantic type is wrong.
52. Machine Translation Risk Patterns
Automatic systems can handle common temporal phrases fluently yet fail on ambiguity, nested timelines and long-distance scope. Since may be rendered causally when temporal, while contrastively when simultaneous, or until as a simple endpoint without continuation. Systems may also normalize complex past relations in ways that erase relative order.
Human review should prioritize sentences with two or more temporal markers, deadlines, negative temporal phrases, before-clauses with unrealized events, and procedures where order affects safety. Search tools can locate visible markers, but only timeline reconstruction verifies meaning.

54. Frequently Asked Questions
Are before and after exact opposites?
They reverse precedence, but their clauses can differ in event actuality and discourse behaviour. A before-clause can sometimes describe an event that never actually occurs.
What is the difference between by and until?
By normally sets a latest completion time; until describes continuation up to a boundary. They should not be translated as interchangeable.
How do I know whether since means time or cause?
Try replacing it with from the time that and then with because. Context will usually show which relation fits.
Does while always mean simultaneous?
No. It can also mark contrast, similar to whereas. The relation must be identified from context.
Should future time clauses keep the same tense?
Not necessarily. Languages differ in future marking. Preserve the event relation and temporal dependency rather than forcing identical tense forms.
What is the fastest way to verify event order?
Draw a simple timeline, then draw the timeline implied by the target. If the order, overlap, boundaries or event actuality differ, revise.
Why are temporal connectives important in instructions?
Because they determine action order, waiting periods, measurement windows and trigger points. A small temporal error can make a correct procedure unsafe or ineffective.
55. Where This Fits in the eduKate Translation Architecture
Use Tense, Aspect and Time when the main difficulty is verb tense or grammatical viewpoint. Use Lexical Aspect and Telicity for states, activities, accomplishments, achievements and event boundaries. Use Negation and Scope for not until, not yet and no longer. Use Discourse Relations and Connectives when since, while or as carries a causal or contrastive rather than temporal relation. Use Master Art of Translation for the complete system.
56. Final Principle: Translate the Timeline, Not the Time Word
A precise translation of temporal connectives preserves the geometry of events: precedence, succession, overlap, continuation, duration, threshold and deadline. The target can reorder clauses, change tense forms, replace a connective with a particle or divide one sentence into several. Those are legitimate adaptations when the same timeline remains recoverable.
When a temporal sentence becomes difficult, stop asking which target word means before or since. Ask what happened first, what was already in progress, what continued, what ended, what had not yet happened and which event activated the next one. Draw it. Verify it. Then write it naturally. A good translation lets the reader inhabit the same timeline as the source.
