-(으)ㄹ게요

Build it

When to use it

-(으)ㄹ게요 is a commitment made to someone: 제가 도와줄게요 (I’ll help you), 내일 전화할게요 (I’ll call you tomorrow). It responds to the listener’s situation, which is why it feels warm where -겠- feels formal.

Three restrictions follow from that. The subject must be I or we, since you cannot promise on someone else’s behalf. It takes action verbs only. And it cannot be a question — 갈게요? does not exist; use -(으)ㄹ까요? instead.

Attachment is the standard rule with the ㄹ short form: 만들다 gives 만들게요. Note the spelling — it is pronounced [께요] but always written 게요.

How to attach it

In use

Compared with

• -(으)ㄹ 거예요

  -(으)ㄹ 거예요 reports a plan that stands whether or not you are talking to anyone. -(으)ㄹ게요 is shaped by the conversation and often adjusts to what the other person just said.

  내일 부산에 갈 거예요. (my plan)  /  그럼 제가 갈게요. (in that case, I’ll go)

• -겠-

  Same promise, different setting. -겠습니다 is what you say in a meeting or to a client; -(으)ㄹ게요 is what you say to a colleague or a friend.

  제가 하겠습니다. (formal)  /  제가 할게요. (everyday)

• -(으)ㄹ래요

  -(으)ㄹ래요 expresses what you feel like doing, with no obligation attached. -(으)ㄹ게요 makes a commitment the listener can hold you to.

  저는 집에 갈래요. (I’d rather go home)  /  저는 집에 갈게요. (I’ll go home, then)

Watch out

• 저녁은 제가 만들을게요.

  저녁은 제가 만들게요.

  Stems ending in ㄹ already supply it. 살게요, 놀게요, 팔게요 follow the same pattern.

• 동생이 내일 올게요.

  동생이 내일 올 거예요.

  You can only promise for yourself. Someone else’s plan takes -(으)ㄹ 거예요.

• 제가 먼저 갈게요?

  제가 먼저 갈까요?

  This ending cannot ask. To check whether the other person is happy with your suggestion, use -(으)ㄹ까요?
