Korean Future Tense: -(으)ㄹ 거예요 Explained
10-Second Answer
-(으)ㄹ 거예요 attaches to a verb stem to express future plans or predictions — "will [verb]" or "going to [verb]." 가다 (go) → 갈 거예요 ("will go"). Whether you insert 으 before ㄹ depends on the same batchim rule you've already seen elsewhere on this site.
The Pattern
| Stem ends in… | Attach | Example |
|---|---|---|
| a vowel | -ㄹ 거예요 | 가다 → 가 + ㄹ 거예요 → 갈 거예요 |
| a consonant (batchim) | -을 거예요 | 먹다 → 먹 + 을 거예요 → 먹을 거예요 |
Same batchim logic as the particles you already know: vowel-ending stems get the lighter ㄹ-only form, consonant-ending stems need the extra 으 to connect smoothly.
Quick Examples
내일 학교에 갈 거예요.
naeil hakgyo-e gal geoyeyo.
I'll go to school tomorrow.
저녁에 뭐 먹을 거예요?
jeonyeoge mwo meogeul geoyeyo?
What are you going to eat for dinner?
비가 올 거예요.
biga ol geoyeyo.
It's going to rain.
Also works as a prediction, not just a personal plan.
Two Jobs: Plans and Predictions
This pattern covers both "I will do X" (intention) and "X will probably happen" (prediction) — English sometimes distinguishes these more sharply ("I will go" vs "it's probably going to rain"), but Korean's -(으)ㄹ 거예요 handles both naturally.
The Casual and Formal Versions
| Level | Form | Example |
|---|---|---|
| Casual | -(으)ㄹ 거야 | 갈 거야 (will go) |
| Polite | -(으)ㄹ 거예요 | 갈 거예요 (will go) |
| Formal | -(으)ㄹ 겁니다 | 갈 겁니다 (will go) |
Common Mistakes
Mistake #1 — Forgetting the batchim rule
먹다 (consonant-ending stem) needs 을 거예요, not just ㄹ 거예요 attached directly.
Mistake #2 — Only using it for plans, not predictions
It works for both — don't reach for a separate structure just to express "it will probably…"
