Talking About the Future
Express future plans and intentions using -(으)ㄹ 거예요, -겠-, and -(으)ㄹ게요.
Korean has three main future-tense patterns, each with slightly different nuance. -(으)ㄹ 거예요 is the most common 'will' / 'going to' — used for plans and predictions. -겠- is shorter and adds a tone of willingness or commitment (저는 할게요 = 'I'll do it'). -(으)ㄹ게요 attaches to verbs to express a casual commitment to the listener ('I'll do it, you can count on me').
The distinction matters in conversation. 갈 거예요 ('I'm going to go') is a neutral statement about your plan. 갈게요 ('I'll go') makes a promise to the listener. 가겠습니다 (formal) shows polite commitment to a superior. Koreans pick between these in real time based on what feels socially appropriate, and learners often default to one form. Build comfort with all three by drilling them with the same verbs and observing how the meaning shifts.
-(으)ㄹ 거예요 — Plan / Expectation
Used to express a future plan or expectation. Attach -(으)ㄹ 거예요 to the verb stem. If the stem ends in a consonant: -을 거예요. If it ends in a vowel or ㄹ: -ㄹ 거예요.
-(으)ㄹ게요 — Promise / Commitment
Expresses a speaker's promise or intention, often in response to a situation. Only used in first person. If the stem ends in a consonant: -을게요. If it ends in a vowel or ㄹ: -ㄹ게요.
How It Works
Korean has several future forms and they differ by what the speaker is signalling, not just by time. This lesson covers the two you need most.
-(으)ㄹ 거예요 states a plan or expectation. The shape follows the now-familiar split: after a consonant, -을 거예요; after a vowel or ㄹ, -ㄹ 거예요. 가다 gives 갈 거예요, 먹다 gives 먹을 거예요. It is neutral — it simply reports what is going to happen, and it works for other people as well as yourself: 친구가 올 거예요.
-(으)ㄹ게요 is different in an important way: it is a commitment made to the listener, and it only works in the first person. 제가 도와드릴게요 promises help; you cannot say 친구가 도와줄게요, because you cannot make a promise on someone else's behalf. It typically responds to the situation at hand, which is why it feels conversational rather than planned.
The practical contrast is this. 갈 거예요 informs someone of your plan. 갈게요 tells them you are going and implicitly accepts responsibility for it, often as a reply to something they said. Using 거예요 where 게요 belongs sounds oddly detached, as though you were reporting on yourself.
Where You'll Hear It
-(으)ㄹ 거예요 is the form for talking about plans, which is a staple of small talk. 주말에 뭐 할 거예요? ('what are you doing this weekend?') is asked constantly, and answering it is one of the first genuinely conversational exchanges learners manage.
-(으)ㄹ게요 lives in service and workplace interactions. 금방 갈게요 ('I'll be right there'), 내일까지 보내드릴게요 ('I'll send it by tomorrow'), 다시 연락드릴게요 ('I'll contact you again') are all commitments made to a specific listener. In a Korean office this ending is everywhere, because so much of work communication is agreeing to do things.
It also handles leaving politely. 먼저 갈게요 ('I'll head off first') is the standard way to excuse yourself from a gathering, and it carries a note of consideration that 먼저 갈 거예요 would lack entirely.
The adverbs from this lesson pair naturally with the forms. 아마 softens a plan into a likelihood — 아마 갈 거예요 — while 꼭 strengthens a commitment: 꼭 갈게요 reads as a firm promise rather than a stated intention.
Cultural & Language Note
The three future forms differ by commitment, not by time. 을 거예요 states a plan or expectation, 을게요 makes a promise to the listener, and 겠 signals immediate intention or conjecture. Choosing 할게요 over 할 거예요 tells the other person you are doing it for them — a distinction that carries real social weight in Korean workplaces.
Common Mistakes to Avoid
을게요 cannot be used for third parties or in questions — 친구가 갈게요 is wrong because a promise can only be made by the speaker. Learners also use 을 거예요 where a promise is expected, which sounds detached: answering a request with 할 거예요 rather than 할게요 can come across as 'I was going to anyway'.
How to Practice This Lesson
Separate the two by asking who the sentence is aimed at. If you are informing someone of a fact about the future, use 거예요. If you are promising the person in front of you, use 게요. Write five sentences of each type with that test in mind rather than trying to memorise a definition.
The -(으)ㄹ shape is the same one you met in -(으)ㄹ 수 있다 last lesson, so treat it as a single piece of machinery you are reusing rather than a new rule. Drilling consonant-final and vowel-final stems once covers both patterns.
Then memorise three fixed phrases whole: 먼저 갈게요, 금방 갈게요, 다시 연락드릴게요. These are high-frequency social formulas, and having them ready means you can exit conversations and make commitments smoothly long before you can construct the forms freely.
