Progressive -고 있다 in Korean

In Brief

To say that an action is in progress, attach -고 있다 to a verb stem: 먹다 → 먹고 있어요 (“am/is/are eating”). The main verb stays before -고, while 있다 changes for politeness and tense. For the state left after an action, Korean often uses -아/어 있다 instead: 문이 열려 있어요 (“The door is open”).

Overview

The Korean construction -고 있다 presents an action as ongoing. In grammar, this is called the progressive aspect: a way of viewing an event as being in progress rather than simply stating that it happens. You will hear it in questions such as 뭐 하고 있어요? (“What are you doing?”), in descriptions of the current situation, and in reports about something that was underway at a particular time.

This is an A2 pattern, and its basic use is close to English “be + verb-ing”: 공부하고 있어요 means “I am studying” or “They are studying,” depending on context. Korean often leaves out a subject that is already understood, so the form itself does not tell you whether the subject is “I,” “you,” “she,” or “they.”

The comparison with English is useful, but it is not exact. Korean does not require a progressive form every time English uses one, and some Korean combinations describe a continuing state rather than an action unfolding moment by moment. Learn the core rule first; the distinctions involving -아/어 있다, clothing verbs, and state-like verbs are explained separately below.

How It Works

The beginner pattern

Start with the dictionary form of an action verb, remove -다 to find the verb stem (the part that carries the verb’s basic meaning), and add -고 있다.

Dictionary form	Stem	Progressive form	Meaning
먹다	먹-	먹고 있다	to be eating
가다	가-	가고 있다	to be going
읽다	읽-	읽고 있다	to be reading
공부하다	공부하-	공부하고 있다	to be studying
만들다	만들-	만들고 있다	to be making

This formation is unusually regular. The stem does not change for vowel harmony, final consonants, or most irregular verb patterns: 듣다 → 듣고 있다, 돕다 → 돕고 있다, and 쓰다 → 쓰고 있다. That is because -고 begins with a consonant and attaches directly to the stem.

The structure can be understood as:

verb stem + -고 + 있다

The ending -고 links the action to 있다. Historically and structurally, 있다 contributes the idea of continuing or being in a condition. In actual use, however, learn -고 있다 as one progressive construction rather than translating each piece separately.

Conjugate 있다, not the main verb

The main verb remains in the -고 form. Conjugate 있다 to show speech level and tense.

Function	Form with 먹다	Natural English equivalent
Present polite	먹고 있어요	am/is/are eating
Present informal	먹고 있어	am/is/are eating
Present formal	먹고 있습니다	am/is/are eating
Past polite	먹고 있었어요	was/were eating
Future or prediction	먹고 있을 거예요	will probably be eating

In 먹고 있었어요, the past marking belongs to 있었어요, not to 먹다. Avoid forms that try to put a past ending before -고 when the intended meaning is simply “was doing.”

The future form -고 있을 거예요 usually predicts that an action will be in progress: 내일 이 시간에는 일하고 있을 거예요 means “At this time tomorrow, I’ll be working.” For a simple future action, Korean normally uses a simple future expression instead.

Questions and negatives

Korean forms a polite question mainly through intonation in speech and a question mark in writing:

• 지금 일하고 있어요. — “I’m working now.”
• 지금 일하고 있어요? — “Are you working now?”

Two common negative patterns are available:

• 안 + verb + -고 있다: 지금 안 자고 있어요. — “I’m not sleeping now.”
• verb + -고 있지 않다: 지금 자고 있지 않아요. — “I’m not sleeping now.”

The first is especially common in everyday conversation. Be careful with its practical meaning: 안 먹고 있어요 may mean “I’m not eating” or, in context, “I have been avoiding/not having it,” not merely that no bite is entering the speaker’s mouth at that exact second.

Ongoing action versus resultant state

The most important contrast is between -고 있다 and -아/어 있다.

• -고 있다 usually focuses on an action in progress: 문을 열고 있어요 — “Someone is opening the door.”
• -아/어 있다 usually focuses on the resulting condition after a completed change: 문이 열려 있어요 — “The door is open.”

A resultant state is simply the condition that remains after something happens. The door first opens; afterward, it remains open. Korean commonly uses -아/어 있다 with an intransitive verb—a verb whose subject undergoes the change and which does not take a direct object in that use—such as 열리다 (“to open/be opened”), 닫히다 (“to close/be closed”), 앉다 (“to sit down”), or 서다 (“to stand up”).

Focus	Korean	Meaning
Action in progress	민수가 문을 열고 있어요.	Minsu is opening the door.
Resulting state	문이 열려 있어요.	The door is open.
Action in progress	지수가 의자에 앉고 있어요.	Jisu is in the process of sitting down.
Resulting posture	지수가 의자에 앉아 있어요.	Jisu is sitting on a chair.

English “is sitting” looks progressive, but Korean normally describes the maintained posture with 앉아 있다. This is a good reminder not to choose the Korean form solely by looking for “-ing” in an English translation.

Common Mistakes

Putting the tense on the first verb

• Wrong: 먹었고 있어요.
• Right: 먹고 있었어요.
• Why: For “was eating,” keep 먹다 as 먹고 and put the past tense on 있다: 있었어요.

Treating -고 있다 as mandatory whenever English has “-ing”

• Unnatural in many contexts: 저는 학생이고 공부하고 있어요 when you only mean “I study” as a general fact.
• Better: 저는 학생이고 한국어를 공부해요. — “I’m a student and I study Korean.”
• Why: Korean simple present can describe habits, facts, and scheduled activity. Use -고 있다 when the ongoing viewpoint matters, whether now or over a current period.

Using -고 있다 for a state left by a completed change

• Wrong for the intended state: 문이 열고 있어요.
• Right: 문이 열려 있어요.
• Why: 열다 is transitive—it takes an object, as in “open the door.” The door’s resulting state uses 열리다 → 열려 있다. 문을 열고 있어요 instead means that someone is in the process of opening the door.

Conjugating both verbs

• Wrong: 공부해요고 있어요.
• Right: 공부하고 있어요.
• Why: Remove -다 from 공부하다, add -고, and conjugate only 있다.

Using 있다 instead of 계시다 for an honored subject

• Less respectful: 할아버지가 주무시고 있어요.
• More appropriate: 할아버지가 주무시고 계세요.
• Why: When the subject deserves honorific treatment, 계시다 replaces 있다. The honorific verb 주무시다 also replaces 자다 (“to sleep”). Honorific choice depends on the social relationship and situation.

Usage Notes

“Right now” is not the only time frame

Although 지금 (“now”) often appears with the progressive, -고 있다 can cover an activity continuing around the present: 요즘 새 직장을 찾고 있어요 (“I’m looking for a new job these days”). The person does not need to be searching at the exact moment of speaking. Context determines the size of the ongoing period.

Simple present can still sound natural

Korean often uses the simple present where English prefers a progressive, especially for ordinary questions and immediate actions. For example, 어디 가요? is the normal “Where are you going?”; 어디 가고 있어요? is possible but gives extra attention to the journey already in progress. Similarly, 뭐 해요? may ask “What are you doing?” while 뭐 하고 있어요? makes the ongoing situation explicit.

Speech level changes the ending

-고 있어요 is polite and broadly useful. -고 있어 is casual and suitable with close friends or people to whom casual speech is appropriate. -고 있습니다 is formal and common in reports, announcements, presentations, and customer-facing language. The progressive meaning remains the same; the relationship and setting change.

Subjects are often omitted

공부하고 있어요 can mean “I’m studying,” “she’s studying,” or “they’re studying.” Korean relies heavily on shared context. Do not add 저는 or another subject to every sentence merely because English requires one.

Beyond the Basics / Advanced Use

You do not need to master every item in this section at A2, but these patterns explain forms you will encounter often.

Verbs that develop state-like meanings

Some combinations with -고 있다 are conventionally understood as continuing states:

• 알고 있다 — to know, literally to have come to know and retain that knowledge
• 살고 있다 — to live/reside
• 가지고 있다 — to have/possess
• 기억하고 있다 — to remember/keep in mind

Their natural English translations often use simple present, not “be ...-ing.” 그 사람을 알고 있어요 means “I know that person,” not normally “I am knowing that person.”

Clothing and attachment verbs

With verbs such as 입다 (“put on clothes”), 쓰다 (“put on a hat/glasses”), 신다 (“put on footwear”), and 차다 (“put on/wear an accessory”), -고 있다 usually describes the maintained result:

• 안경을 쓰고 있어요. — “She is wearing glasses.”
• 검은 구두를 신고 있어요. — “He is wearing black shoes.”
• 시계를 차고 있어요. — “She is wearing a watch.”

This differs from the more general action/result contrast above. Context can highlight the act of putting something on, but ordinary 입고 있다 is normally understood as “be wearing.” Korean grammar groups meanings according to how particular verbs are used, so memorize these as common combinations.

Progressive passive forms

A passive verb can also take -고 있다 when a process is underway: 새 다리가 건설되고 있어요 means “A new bridge is being built.” Here 건설되다 is the passive verb (“to be constructed”), and -고 있다 presents the construction as ongoing. By contrast, a completed bridge that remains built would normally be described in another way according to context, not by blindly replacing the ending.

Honorific progressive

For an honored subject, use -고 계시다:

Speech level or tense	Example	Meaning
Polite	기다리고 계세요	is waiting
Formal	기다리고 계십니다	is waiting
Past polite	기다리고 계셨어요	was waiting

Do not use 계시다 merely because you are speaking politely to the listener. It honors the grammatical subject of the sentence. When asking the listener directly in polite service language, the listener is the subject, so 지금 기다리고 계세요? may indeed be appropriate.

Emphasis with 계속 and 아직도

Adverbs sharpen the progressive meaning. 계속 means “continuously/keep on,” while 아직도 means “still,” often with a sense that the situation has lasted longer than expected:

• 계속 비가 오고 있어요. — “It keeps raining.”
• 아직도 일하고 있어요. — “I’m still working.”

The progressive itself does not necessarily mean uninterrupted action. 이 책을 읽고 있어요 can mean that you are partway through the book even if it is currently closed on your desk.

Practice Tips

1. Build three forms from each new action verb. For example: 읽고 있어요, 읽고 있었어요, 읽고 있을 거예요. This trains you to leave the main verb unchanged and conjugate 있다.
2. Describe a scene twice. First name an action in progress—민수가 문을 열고 있어요—then its result—문이 열려 있어요. Use doors, windows, chairs, pictures, and lights to make the contrast concrete.
3. Listen for omitted subjects and time adverbs. When you hear 지금, 요즘, 계속, or 아직도, note whether the speaker uses -고 있다 and infer the subject from context rather than waiting for a pronoun.
