Korean Future Tense: -겠-, -(으)ㄹ 거예요, and Present

English learners arrive with one box labelled will. Korean does not keep that box.

Three ways to talk about later

Same clock time; different speaker stance.

-(으)ㄹ 거예요

Build it from the future modifier + 거예요:

가다 → 갈 거예요
먹다 → 먹을 거예요
하다 → 할 거예요

This is the form most beginners should default to for personal plans.

저녁에 친구를 만날 거예요.
I’m going to meet a friend in the evening.

-겠-

Covered in full on its grammar page. Short version for this contrast:

• outlook: 비가 오겠습니다 (often 합니다체 on boards)
• guess: 피곤하겠어요
• resolve: 열심히 하겠습니다

If you replace every plan with -겠-, you will sound like you are constantly predicting or swearing oaths.

Present for schedules

기차는 오전 9시에 출발해요.
The train leaves at 9 a.m.

Korean is comfortable putting fixed timetable facts in 해요체 present. English “leaves” does the same job; learners still over-insert will.

The curriculum footnote

-(으)ㄹ 거예요 is everywhere in beginner classrooms. On the King Sejong Institute grammar tables we mapped for this site, it does not get its own slot — which is why you will not see it as a separate card on the curriculum map. That is a table fact, not a claim that the form is rare.

So this post exists to do the job a missing slot cannot: put the three stances on one page and send you to -겠- for depth. Soft “probably / I reckon” talk lives on -을 것 같다. Forecast frames are practised on a live board in How to Read a Korean Weather Forecast.

Quick self-test

Translate these with stance, not with a single English will:

1. I’m meeting Mina tomorrow (plan).
2. It looks like it will rain (outlook).
3. The class starts at two (timetable).

If all three come out as -겠-, rewrite.
