To translate Korean -고 있다 (go itda) and -아/어 있다 (a/eo itda) correctly, ask whether the sentence depicts an action currently unfolding or a state that remains after a change. Korean progressive grammar frequently uses -고 있다 for an activity in progress, while -아/어 있다 often describes a resulting state with suitable intransitive or passive change-of-state verbs. English ‘is sitting’, ‘is opening’, ‘is open’ and ‘is wearing’ do not map onto these endings one for one. The verb and the event timeline determine the right translation.
The practical error is temporal. A person who is sitting on a chair is not necessarily still performing the movement of sitting down. A door that is open is not necessarily opening. Conversely, ‘the window is opening’ describes a change in progress, not a completed open condition. Korean-to-English translation loses important information when a generic English ‘-ing’ is applied to every source verb without examining whether a change has happened.
This guide focuses on Korean action versus resulting-state translation, including -고 있다, -아/어 있다, common verb exceptions, tense, natural English and error checks. Use the first-principles explanation, the worked paired examples, independent practice and FAQs. Separate eduKateSG owners handle Korean topic/subject markers, causal endings, numbers and other translation problems, so each page answers a different search question.
Quick answer: progressive action or persistent result?
Use -고 있다 when the speaker is presenting an action as ongoing: 책을 읽고 있어요 (‘I am reading a book’), 비가 오고 있어요 (‘It’s raining’), 창문이 열리고 있어요 (‘The window is opening’). Use -아/어 있다 with suitable verbs when the resultant condition persists: 창문이 열려 있어요 (‘The window is open’), 사람이 앉아 있어요 (‘Someone is seated’), 불이 꺼져 있어요 (‘The light is off’).
The distinction is not an absolute rule that -고 있다 can never describe a state. Korean conventional expressions such as 안경을 쓰고 있어요 (‘is wearing glasses’) and 옷을 입고 있어요 (‘is wearing clothes’) show a lasting condition with -고 있다. The correct method therefore asks about the meaning of the verb, its transitivity, common construction and communicative focus, rather than relying on the English ending alone.
First principles: time, aspect, result and observation
Tense and aspect do different jobs
Tense locates a situation in time; aspect presents its internal temporal structure. The present polite form 있어요 may occur in both constructions, while the endings before 있다 decide whether the action is presented in progress or its result is in force. A fluent English translation may use a present progressive, a simple state predicate or a present perfect according to the actual relationship.
An action can have stages
Opening a door has an initial closed condition, an opening event and an eventual open condition. ‘열리고 있어요’ points to the process, while ‘열려 있어요’ points to the state after the door has opened. The event may have finished before the moment being described. Translation must identify which stage is relevant before selecting ‘opening’ or ‘open’.
State does not mean permanent
A window can be open now but closed later. ‘열려 있어요’ describes a maintained result at the relevant time, not an eternal property. A translator should avoid adding ‘always’ or ‘permanently’. The same applies to a person standing, lights being on, and a cup remaining broken; the ongoing condition has a boundary in time even if the sentence does not specify it.
-고 있다 is broader than English progressive
It can describe a currently ongoing event and, with certain verbs, a continuing state or habitual period. ‘서울에서 살고 있어요’ may mean ‘I live in Seoul’ rather than ‘I am in the act of living’. Korean clothing and possession-like expressions often use -고 있다 while English naturally says ‘is wearing’. Do not force a process interpretation every time.
-아/어 있다 is selective
The resulting-state construction commonly attaches to suitable intransitive change-of-state predicates and passives such as 열리다, 닫히다, 켜지다 and 앉다. It is not a universal alternative that can be placed after any activity verb. For ordinary eating or reading, -고 있다 is appropriate for the event in progress; ‘먹어 있어요’ is not a standard substitute for ‘is eating’.
Transitivity changes the analysis
A transitive verb typically has an object undergoing an action, while an intransitive or passive change-of-state predicate allows the subject itself to display the result. Compare 문을 열고 있어요 (‘someone is opening the door’) with 문이 열려 있어요 (‘the door is open’). The subject and verb differ; translation must not hide who did what, if the source identifies an agent.
English participles can be ambiguous
‘The door is closed’ can be a state; ‘the door is being closed’ is a process. ‘He is sitting’ usually denotes posture, not the short movement into a seat. Korean more overtly distinguishes some of these views. A translator should sometimes choose a different English grammar form to preserve Korean aspect rather than matching surface endings.
Perspective determines what the reader learns
A maintenance notice saying 불이 꺼져 있어요 reports the lights are off; a notice saying 불이 꺼지고 있어요 reports the lights are going out. The first describes the present condition, while the second describes a change. Confusing them can mislead people about the sequence of an outage or repair.
Completed action versus continuing aftermath
-아/어 있다 places attention on a resulting condition, but it does not itself certify the identity of the person who caused the change. ‘문이 잠겨 있어요’ describes a locked door; it does not prove who locked it or why. This boundary is essential in incident reports and factual translations.
The English tense may vary by discourse
A past context can produce ‘was reading’ from -고 있었어요 or ‘was open’ from 열려 있었어요. The auxiliary 있다 bears tense and style marking; the clause’s surrounding time phrase determines how a translator locates the observation. Retain the timeline even when English word order is reorganised.
Habit and ongoing occupation require care
‘지금 일하고 있어요’ describes working right now, but ‘회사에서 일하고 있어요’ may describe current employment. English may use ‘I’m working’ or ‘I work’ depending on the discourse. An apparently literal present progressive can miscommunicate when a Korean source describes a relatively stable situation.
A reliable translator recognises exceptions
Verbs such as 입다 and 쓰다 can form ongoing wearing states with -고 있다. Memorising a simplistic ‘ongoing = -고; state = -어’ rule is not enough. Build a record of conventional verb constructions and test each new sentence against authentic usage before standardising a translation in professional material.
The twelve-stage method: from Korean source to faithful English
1. Find the main lexical verb
Separate the lexical stem from its aspect construction, politeness ending and tense. In 열려 있어요, identify 열리다 as a change-of-state verb; in 읽고 있어요, identify 읽다 as the reading action. If you misidentify the stem, all later analysis may be wrong even when you recognise 있다.
2. Draw the event timeline
Write three positions: before the change, change in progress and state afterward. Place the source sentence at the correct point. This simple model is more dependable than translating each particle into a separate English word. It exposes the difference between opening and open immediately.
3. Check the ending as a whole
Read -고 있다 and -아/어 있다 as constructions, not as isolated ‘and’ and ‘exist’ words. Their meanings are distributed across the verbal sequence. Check for contractions and tense forms such as -고 있었어요, -어 있었어요 and polite clause endings before drafting.
4. Inspect the subject and object
Look for markers including 이/가 and 을/를. ‘문을 열고 있다’ presents someone opening a door, while ‘문이 열려 있다’ presents the door as the subject whose state matters. A translator must not introduce a new agent where the Korean sentence does not assert one.
5. Decide whether the event is still unfolding
If an action is visibly in progress, English often uses ‘is reading’, ‘is running’, ‘is opening’, or ‘is writing’. Ask whether the source indicates motion or activity happening at the reference time. A resulting-state clause does not need that process gloss.
6. Test for a persisting result
If the subject has changed to a state and remains there, translate the current condition: ‘is open’, ‘is closed’, ‘is seated’, ‘is standing’ or ‘is locked’. The exact English wording depends on what state is being maintained. Avoid an action-in-progress paraphrase unless other context establishes it.
7. Look for conventional -고 state verbs
If the verb means putting on or wearing an item, Korean -고 있다 can report the wearing state: 옷을 입고 있어요. The English ‘is putting on clothes’ would describe a different stage from ‘is wearing clothes’. Use the conventional sense supported by the verb and immediate context.
8. Locate the reference time
Check now, yesterday, at that moment, still, already and other temporal expressions. An observed open state yesterday is not a present open state today. Do not erase the timeframe when rewriting Korean forms into natural English tenses.
9. Check whether the result implies an agent
Passive and intransitive constructions may describe a state without identifying its cause. ‘문이 열려 있어요’ does not tell us whether a person opened the door or the wind moved it. If the source does not assign agency, avoid inventing an actor in the translation.
10. Compare nearby clauses
An earlier sentence may narrate the opening; a later sentence may describe the open state. Keeping both allows the reader to recover the sequence. If you translate both as ‘the door is opening’, you collapse the chronology and lose the change that connects the sentences.
11. Run an English naturalness pass
Use ‘is open’, ‘is seated’, ‘is wearing glasses’, ‘has stopped’ or ‘is waiting’ as context dictates. English may use a past participle or a progressive without mapping directly to the Korean affix. Naturalness is legitimate when it preserves both time and event structure.
12. Back-check with a minimal pair
Change the Korean construction where grammatical and compare the resulting meaning: 열리고 있어요 versus 열려 있어요. Ask whether the English sentences change correspondingly. Record the exception when a form such as 입고 있어요 retains a state reading. Reuse the test on a new verb before treating the pattern as mastered.
Worked Korean examples: motion, activity, posture and lasting condition
Example 1: 지금 책을 읽고 있어요.
Natural English: I’m reading a book right now.
Grammar decision: Reading is the activity underway at the reference moment.
Meaning boundary: The sentence does not say the book has been finished.
Example 2: 밥을 먹고 있어요.
Natural English: I’m eating.
Grammar decision: 먹다 describes the ongoing eating event, a regular use of -고 있다.
Meaning boundary: It should not become ‘I have eaten’.
Example 3: 편지를 쓰고 있어요.
Natural English: I’m writing a letter.
Grammar decision: Writing is proceeding but no completed letter is asserted.
Meaning boundary: Do not turn it into ‘I’ve written the letter’.
Example 4: 비가 오고 있어요.

Grammar decision: Rainfall is an ongoing weather event.
Meaning boundary: The clause gives no forecast for when the rain will stop.
Example 5: 친구가 기다리고 있어요.
Natural English: My friend is waiting.
Grammar decision: 기다리다 describes a maintained waiting activity.
Meaning boundary: ‘Has arrived’ is not implied by waiting.
Example 6: 문이 열리고 있어요.
Natural English: The door is opening.
Grammar decision: 열리다 with -고 있다 presents a change underway.
Meaning boundary: The door may not yet be fully open.
Example 7: 문이 열려 있어요.
Natural English: The door is open.
Grammar decision: 열려 있다 presents the resulting open state.
Meaning boundary: The statement alone does not identify who opened it.
Example 8: 창문이 닫히고 있어요.
Natural English: The window is closing.
Grammar decision: The process of becoming closed is in progress.
Meaning boundary: It is not necessarily closed yet.
Example 9: 창문이 닫혀 있어요.

Grammar decision: The present condition is the result of a closing event.
Meaning boundary: Do not substitute ‘is being closed’ without evidence.
Example 10: 불이 켜지고 있어요.
Natural English: The light is coming on.
Grammar decision: A change from off to on is happening.
Meaning boundary: The phrase does not establish that the light is already steadily on.
Example 11: 불이 켜져 있어요.
Natural English: The light is on.
Grammar decision: The resulting state is lit or powered on.
Meaning boundary: The actor or mechanism that switched it on is not specified.
Example 12: 불이 꺼지고 있어요.

Grammar decision: The process of switching or going off is underway.
Meaning boundary: An in-progress outage is different from a completed off state.
Example 13: 불이 꺼져 있어요.

Grammar decision: The off condition now holds.
Meaning boundary: Do not infer that a power failure caused the condition.
Example 14: 의자에 앉아 있어요.

Grammar decision: 앉아 있다 describes the seated posture that remains after sitting down.
Meaning boundary: English ‘I’m sitting’ is natural even without describing the downward motion.
Example 15: 학생들이 앉고 있어요.
Natural English: The students are sitting down.
Grammar decision: 앉고 있다 highlights the movement into the seated position.
Meaning boundary: Translate the activity, not simply the resulting posture.

Grammar decision: 서 있다 describes an upright state at the location.
Meaning boundary: The sentence does not claim that the person is currently rising to stand.
Example 17: 사람들이 줄을 서고 있어요.

Grammar decision: 서 있다 reports the standing or queued state already established.
Meaning boundary: Do not remove the queue relation from the English.
Example 19: 아기가 자고 있어요.
Natural English: The baby is sleeping.
Grammar decision: Sleep is treated as an ongoing state/activity with 자고 있다.
Meaning boundary: The English -ing form is natural here; no result phrase is needed.
Example 20: 아이가 웃고 있어요.

Meaning boundary: The source does not tell us the child’s mood beyond the observed expression.
Example 21: 안경을 쓰고 있어요.
Natural English: I’m wearing glasses.
Grammar decision: 쓰고 있다 commonly conveys the wearing state of glasses.
Meaning boundary: A blind ‘putting on glasses’ translation may describe the wrong event stage.
Example 22: 모자를 쓰고 있어요.
Natural English: I’m wearing a hat.
Grammar decision: The conventional clothing construction describes a worn item.
Meaning boundary: Use ‘putting on’ only if surrounding context clearly indicates that motion.
Example 23: 옷을 입고 있어요.
Natural English: I’m wearing clothes.
Grammar decision: 입고 있다 often means that the clothes are on.
Meaning boundary: It does not necessarily mean the person is dressing right now.
Example 24: 옷을 입고 있는 사람이에요.
Natural English: It’s the person wearing the clothes.
Grammar decision: The -고 있는 modifier identifies a person by present clothing.
Meaning boundary: Clarify which clothes if context provides the description.
Example 25: 서울에서 살고 있어요.
Natural English: I’m living in Seoul.
Grammar decision: 살고 있다 can describe current residence over a period.
Meaning boundary: ‘I live in Seoul’ may be more idiomatic in many contexts.
Example 26: 한국어를 배우고 있어요.
Natural English: I’m learning Korean.
Grammar decision: The learning process is in progress or ongoing these days.
Meaning boundary: It does not prove fluency or a completed course.
Example 27: 지금 공부하고 있어요.
Natural English: I’m studying right now.
Grammar decision: The adverb 지금 fixes the current activity reading.
Meaning boundary: Avoid changing it into a general statement about academic status.
Example 28: 회사가 새 건물을 짓고 있어요.
Natural English: The company is building a new building.
Grammar decision: Construction is presented as ongoing, with a company agent.
Meaning boundary: The source does not say the building has been completed.
Example 29: 차가 멈춰 있어요.
Natural English: The car is stopped.
Grammar decision: The car is in a resulting stopped condition.
Meaning boundary: The sentence alone cannot prove why it stopped.
Example 30: 문이 잠겨 있어요.
Natural English: The door is locked.
Grammar decision: 잠겨 있다 describes the locked condition.
Meaning boundary: Do not invent a person or policy that caused the locking.
Example 31: 책이 펼쳐져 있어요.
Natural English: The book is open.
Grammar decision: The book is in an opened or spread-out condition.
Meaning boundary: Do not confuse this with someone actively opening the book.
Example 32: 꽃이 피어 있어요.
Natural English: The flowers are in bloom.
Grammar decision: 피어 있다 focuses on the state after blooming.
Meaning boundary: The flowers need not be actively opening at that second.
Example 33: 컵이 깨져 있어요.
Natural English: The cup is broken.
Grammar decision: The damage remains as a result.
Meaning boundary: The sentence gives no evidence of who broke it or when.
Example 34: 아직 자리가 남아 있어요.

Grammar decision: 남아 있다 reports an available remainder.
Meaning boundary: Do not claim a specific seat has been reserved.
Example 35: 지금 전화하고 있어요.
Natural English: I’m on the phone right now.
Grammar decision: The ongoing telephone activity can be phrased naturally as an English situation.
Meaning boundary: This does not identify the person on the other end.
Example 36: 회의를 하고 있어요.
Natural English: We’re having a meeting.
Grammar decision: The meeting is ongoing.
Meaning boundary: The sentence alone does not state its agenda or decisions.
Example 37: 직원들이 일하고 있어요.
Natural English: The employees are working.
Grammar decision: Work activity is ongoing; the setting determines whether it is now or these days.
Meaning boundary: Do not infer permanent employment from one moment of work.
Example 38: 그는 아직 앉아 있어요.
Natural English: He’s still seated.
Grammar decision: 아직 highlights the continuation of a posture.
Meaning boundary: It does not indicate when the person sat down.
Example 39: 그들은 이미 도착해 있어요.
Natural English: They have already arrived and are there.
Grammar decision: The resulting presence is in view, rather than the journey in progress.
Meaning boundary: Translate with care: ‘have arrived’ alone may suffice when location is understood.
Example 40: 문을 열고 있어요.
Natural English: Someone is opening the door.
Grammar decision: The transitive 열다 places an agent’s action on the door, with the agent understood from context.
Meaning boundary: Do not confuse 문을 with 문이 and accidentally remove the actor.
Example 41: 문을 닫고 있어요.
Natural English: Someone is closing the door.
Grammar decision: The transitive form expresses ongoing closure by an agent.
Meaning boundary: A completed closed state would need different wording.
Example 42: 열쇠가 문에 꽂혀 있어요.
Natural English: The key is inserted in the door.
Grammar decision: The state is that the key is already in position.
Meaning boundary: It is not necessarily being inserted at the moment.
Example 43: 모두 조용히 기다리고 있어요.
Natural English: Everyone is waiting quietly.
Grammar decision: The action continues, and 조용히 describes how it occurs.
Meaning boundary: A translation should preserve the manner without adding a time limit.
Common failures and precise repairs
1. Translating 열려 있다 as ‘is opening’
This loses the completion of the change and implies motion now. ‘The door is open’ is the usual English rendering of a lasting open state. Repair by placing the source on the three-part timeline: closed, opening, open. Identify whether the verb reports the transition or the condition after it.
2. Translating 열리고 있다 as ‘is open’
The progressive of a change verb says a transition is unfolding. In a building or service notice, confusing opening with open may lead a reader to believe access already exists. Keep process and endpoint distinct, especially when the sentence is part of safety or access information.
3. Treating every -고 있다 as physical motion
Wearing and other conventional verbs make this unsafe. ‘안경을 쓰고 있어요’ commonly means ‘is wearing glasses’, not ‘is putting them on’. Check the verb’s lexical behaviour and known construction rather than enforcing a single English tense for every instance of -고.
4. Attaching -아/어 있다 to any transitive activity verb
The resulting-state pattern is not a universal synonym of progressive ‘be -ing’. Read and write are ordinary activities, whereas the state construction often uses intransitive change predicates. Use authentic verb-pattern evidence before applying the ending and avoid inventing forms in learning materials.
5. Ignoring subject markers and transitivity
‘문을 열고 있어요’ involves opening the door; ‘문이 열려 있어요’ reports that the door is open. One clause has an object, the other a subject in a state. Translating both as ‘the door opens’ eliminates both agency and aspect distinctions.
6. Assuming English -ing always reports an ongoing action
English ‘He is sitting’ normally describes posture, while Korean distinguishes the moment of sitting down from the maintained seated state. Ask what the real-world timeline is, not whether the English sentence contains an -ing word. Translating concepts comes before matching endings.
7. Adding an agent to a passive state
A locked or open door may have changed through many causes, but the source state description does not always name one. ‘The door is locked’ is safer than ‘the guard locked the door’ unless the latter appears in the source. This distinction matters in incident documentation.
8. Erasing time reference
‘닫혀 있었어요’ can mean the door was closed at the referenced past time. Translating it as ‘is closed’ shifts an observation into the present. Mark tense on 있다 and any explicit adverbs before selecting an English form. Do not let a natural-sounding sentence hide a changed timestamp.
9. Confusing ‘already’ and ‘still’
이미 and 아직 can describe whether a change has happened or a state persists. They are not interchangeable. ‘Still seated’ and ‘already seated’ describe different relationships to expectation. Keep the adverb as part of the timeline rather than dropping it during stylistic editing.
10. Overreading a completed result as permanent
A light that is off can later turn on; a window that is open can later close. The resulting-state construction holds at the reference moment and does not assert permanent status. Avoid absolute expressions such as always, forever or irreversibly unless the source supports them.
11. Mistaking habitual work for an immediate task
‘서울에서 일하고 있어요’ may describe current employment, while ‘지금 일하고 있어요’ clearly refers to working now. A translation that always says ‘I am working this second’ could misstate the context. Check location, time adverbs and discourse purpose.
12. Collapsing a two-sentence sequence
One sentence might say ‘the window was opening’ and the next ‘it remained open’. A summary that renders both as ‘the window opened’ loses process and result. Preserve sequence and transitions when the source is narrative, technical or explanatory.
13. Making a medical or safety inference from aspect
‘The person is sitting’ is not evidence that they are well, uninjured or resting voluntarily. ‘The light is off’ is not proof of an electrical failure. Translate the state actually observed and avoid diagnosing causes or consequences from a grammatical form.
14. Neglecting the final audience
A bilingual learner may understand a literal gloss such as ‘exists having opened’, but a general English reader expects ‘is open’. Use linguistic notes in analysis and natural phrasing in the final answer. Then check that the final English retains the source’s event stage, actor and time.
15. Assuming there is only one accepted English rendering
‘서 있어요’ can read as ‘is standing’ or, in some contexts, ‘stands there’; ‘살고 있어요’ can be ‘I live’ or ‘I am living’. The best translation matches the time frame and genre. Avoid marking every alternative wrong when it preserves the same information.
Guided Korean practice with answer explanations
For each source sentence, draw a simple timeline and label it ‘process’ or ‘remaining state’. Then translate it naturally. The explanations give the diagnostic reason, not just a corrected string. Where an English form is flexible, preserve event structure first.

Frequently asked questions
What is the simplest difference between -고 있다 and -아/어 있다?
-고 있다 commonly highlights an action in progress, while -아/어 있다 with suitable verbs highlights a condition resulting from a change. The difference is clearest in ‘열리고 있어요’ (‘is opening’) versus ‘열려 있어요’ (‘is open’). English may choose very different verb forms for each.
Why is 앉아 있어요 translated as ‘is sitting’?
Korean describes the posture that remains after the person sat down. English commonly uses the -ing form ‘is sitting’ for this state, even though the downward movement has finished. This is a useful warning against matching Korean and English grammar by their visible endings.
Can -고 있다 describe a state?
Yes. Clothing expressions such as ‘안경을 쓰고 있다’ commonly describe wearing glasses. Some other verbs also form ongoing situation readings that are not momentary motion. Read authentic usage and the verb’s meaning; an absolute process-only rule is too crude.
Does -아/어 있다 work with every verb?
No. It typically combines with appropriate intransitive or passive change-of-state verbs to depict a persisting condition. Ordinary activity predicates such as eating or reading normally use -고 있다 for the ongoing event. Learn common pairings instead of generating forms mechanically.
What is the difference between 문을 열고 있다 and 문이 열려 있다?
The first presents an agent opening the door and uses a transitive object. The second presents the door as the subject in an opened state. The English should reflect both agency and aspect: ‘is opening the door’ versus ‘the door is open’. One does not substitute freely for the other.
Why does English sometimes use ‘is open’ instead of ‘is opening’?
English separates a stative adjective open from the progressive verb opening. Korean similarly distinguishes the ongoing change from its continuing result, but uses different aspect constructions. The translator chooses the target form that preserves the event stage, not the form that looks morphologically closest.
Can I use this pattern in past tense?
Yes, with appropriate auxiliary tense: ‘읽고 있었어요’ can report an action in progress at a past time, and ‘열려 있었어요’ an open state at a past time. Keep contextual time expressions intact. Past reference does not by itself transform the type of aspect.
Does a resulting-state sentence tell me who caused it?
Generally not unless the agent is separately expressed. ‘문이 닫혀 있다’ focuses the door’s closed condition, not the identity of the person who closed it. A translation that adds a named actor without evidence may create a false factual claim.
How should I translate 안경을 쓰고 있어요?
Normally as ‘is wearing glasses’ when the context describes current appearance. It does not necessarily mean the person is actively putting them on at that moment. This conventional usage is a core exception to over-simple textbook summaries.
Does 살고 있어요 mean ‘is living’ or ‘lives’?
Both can be natural English depending on the context. For a current residence, ‘I live in Seoul’ may sound more ordinary than ‘I’m living in Seoul’. For a temporary arrangement, the progressive may fit. Keep the residence and timeframe, then choose idiomatic English aspect.
What is the role of 이/가 versus 을/를 here?
They help reveal whether a noun is presented as a subject undergoing or displaying a state, or an object affected by another agent’s action. The aspect meaning also depends on the verb. Read them together rather than assuming the ending alone supplies all the needed information.
How can I practise reliably?
Use near-minimal pairs with opening/being open, closing/being closed, sitting down/being seated and lining up/standing in line. Identify before, change and after. Translate both sentences, then ask another reader whether the difference remains visible in English.
What if a dictionary offers several meanings for a verb?
Use the whole sentence and source context. A verb’s transitivity and conventional construction may select a state or process reading. A single English gloss cannot encode the entire aspect system. Record a complete short example with each new verb, not only a word-to-word pair.
Does a state necessarily continue forever?
No. The state holds at the reference moment or over the relevant interval. A door that is open may close later; a person who is seated may stand up. Do not add permanent, always or forever unless a separate source phrase does so.
Where does this guide end?
It owns the narrow distinction between ongoing action and persisting result. Korean topic/focus markers, number systems, honorifics and causal connectors need their own guides. Use the linked companion owners where another grammatical question is central, rather than treating all Korean translation as a single topic.
Transfer: interpreting real-world Korean without inventing events
Consider a museum notice: ‘문이 잠겨 있어요’. It tells a visitor that the door is locked. It does not specify that a guard has just locked it, that the museum is permanently closed or that access will never be restored. A second notice saying ‘문이 닫히고 있어요’ would describe a door closing, a different moment. In multilingual visitor guidance, the distinction between current condition and transition should survive even when the English uses a short adjective.
Consider an image caption: ‘학생들이 줄을 서고 있어요’ differs from ‘학생들이 줄을 서 있어요’. The first may describe people forming a queue; the second describes a line that already exists. English captions can say ‘Students are lining up’ versus ‘Students are standing in line’. Neither caption should add a motive or a destination not shown or stated.
Consider an incident update: ‘불이 꺼져 있었어요’ describes the light as off at a past moment. ‘불이 꺼지고 있었어요’ describes the change to off underway then. Neither form alone diagnoses the electrical cause. The editor should preserve the observed stage, past reference and uncertainty, then include causes only when independently supported by the report.

The final editing question is whether the reader sees a process unfolding or a result continuing. A sound translation preserves that timeline, keeps agents and causes within the evidence, and chooses English that is natural enough to be understood without losing the Korean distinction.
