How It Works

-ㄴ/는/ㄹ 텐데 is a versatile advanced ending used to connect a speaker's supposition with a related thought. It's crucial for expressing nuanced thoughts and creating smoother, more complex sentences.

Conjugation Rules:
The conjugation depends on the tense and the type of word (verb/adjective).

1. Present or Future Supposition: -(으)ㄹ 텐데
This is the most common form. It's used to guess about a present state (with adjectives/이다) or a likely future event (with verbs).

  • Adjectives/이다 (Present State):
    › Adjective stem ending in a vowel + -ㄹ 텐데: 바쁘다 → 바쁠 텐데 (must be busy)
    › Adjective stem ending in a consonant + -을 텐데: 좋다 → 좋을 텐데 (must be good)
    › Noun + -일 텐데: 학생이다 → 학생일 텐데 (is probably a student)
  • Action Verbs (Future Action):
    › Verb stem ending in a vowel + -ㄹ 텐데: 오다 → 올 텐데 (will likely come)
    › Verb stem ending in a consonant + -을 텐데: 먹다 → 먹을 텐데 (will likely eat)

2. Supposition about an Ongoing Action: -고 있을 텐데
To guess that an action is in progress right now, use the -고 있다 form.

  • Action Verb stem + -고 있을 텐데
    › 가다 → 가고 있을 텐데 (is probably going)
    › 읽다 → 읽고 있을 텐데 (is probably reading)

3. Past Supposition: -았/었을 텐데
This form is used to guess about something that has already happened.

  • Verb/Adjective stem + -았/었을 텐데
    › 하다 → 했을 텐데 (must have done)
    › 많다 → 많았을 텐데 (must have been a lot)

Main Usages:

1. Supposition + Contrasting Reality
Used when the reality is different from what was expected.
› 그 식당이 맛있을 텐데 사람이 별로 없네요. (That restaurant is supposed to be delicious, but there aren't many people.)

2. Supposition + Suggestion, Question, or Concern
Used to provide a reason or context for a follow-up question, suggestion, or expression of worry.
› 날씨가 추울 텐데 옷을 따뜻하게 입으세요. (The weather will likely be cold, so please dress warmly.)
› 지금쯤 도착했을 텐데 왜 연락이 없지? (They should have arrived by now, why is there no word from them?)

  1. 밖에 비가 올 텐데 우산 챙겼어요?

    It's probably going to rain outside, did you take an umbrella?

    Word by Word: Outside rain will probably come but did you pack an umbrella?

    The speaker supposes it will rain (올 텐데) and uses this as the basis for asking a question.

  2. 시험공부 하느라 힘들었을 텐데 좀 쉬세요.

    You must have been tired from studying for the exam, so please get some rest.

    Word by Word: Because of studying for the exam must have been tired but rest a bit.

    The speaker makes a supposition about a past situation (힘들었을 텐데) and offers a suggestion based on it.

  3. 김 부장님은 지금 회의 중이실 텐데 나중에 다시 전화해 보세요.

    Mr. Kim is probably in a meeting right now, so try calling back later.

    Word by Word: Manager Kim now is in a meeting probably but later again try calling.

    This uses the honorific -시- with the pattern (중이실 텐데) to make a polite guess about a superior's current situation and give advice.

  4. 이 시간이면 길이 많이 막힐 텐데 지하철을 타는 게 어때요?

    The roads will likely be very congested at this time, so how about taking the subway?

    Word by Word: At this time the road much will be blocked but taking the subway how about it?

    The speaker states a likely situation (막힐 텐데) and makes a suggestion.

  5. 그 영화가 재미있었을 텐데 결국 못 봤어요.

    That movie must have been interesting, but I didn't get to see it in the end.

    Word by Word: That movie must have been interesting but in the end could not see.

    The speaker supposes the movie was good (재미있었을 텐데) and follows it with a contrasting reality (not being able to see it).

Common Mistakes

  • Confusing it with -ㄹ 테니까, which gives a stronger reason for a command.

    Different Meaning내가 도와줄 텐데 걱정하지 마세요.
    Better내가 도와줄 테니까 걱정하지 마세요.

    -ㄹ 테니까 states the speaker's intention as a direct and strong reason for the following command ('I will help you, SO don't worry'). -ㄹ 텐데 is softer; it sets up a situation ('I'll probably help you, and in that context, don't worry'). For direct commands, -ㄹ 테니까 is usually more natural.

  • Using the wrong tense for the supposition.

    Not Quite어제 파티가 재미있을 텐데 못 가서 아쉬워요.
    Better어제 파티가 재미있었을 텐데 못 가서 아쉬워요.

    When making a supposition about a past event (like 'yesterday's party'), you must use the past tense form -았/었을 텐데. The incorrect example uses the future/present supposition form for a past event.

Learn This First

To express expectations with contrast, you need modifier forms and connecting patterns.
