Nesta lição, daremos uma olhada no infixo -겠-. É comumente usado no cotidiano coreano, mas muitas vezes não entendido muito bem pelos aprendizes, principalmente porque ele tem significados e usos muito diferentes.
Vários Usos de -겠-
Você pode usar -겠- para perguntar a intenção de alguém, para expressar o que você está indo fazer, para falar sobre algo que vai acontecer, para expor sua suposição sobre algo, ou para falar sobre possibilidades ou capacidades. Também é frequentemente usado em expressões fixas, tais como 처음 뵙겠습니다 (= Prazer em conhecê-lo.) and 잘 먹겠습니다 (= Thank you for the food.).
1. -시겠어요? / -시겠습니까? = “Would you …?” “Would you like to …?”
This usage is only used in very formal Korean. In more casual Korean, you would use -(으)ㄹ래(요) (Review Level 4 Lesson 2 for this grammar point). The honorific suffix -시- is always used with -겠- in this usage.
Ex)
어디로 가시겠어요?
= Where would you like to go?
Similar: 어디로 갈래(요)?
2. -겠- (used to express one’s intention) = I’m going to …, I’d like to ...
Mostly used in formal Korean, -겠- can also express one’s intention to do something. In more casual Korean, the same meaning can be expressed through -(으)ㄹ게(요) (Review Level 3 Lesson 6 for this grammar point). 
Ex)
제가 하겠습니다.
= I’ll do it.
말하지 않겠습니다.
= I won’t tell you.
3. -겠- (used to express one’s opinion/idea/assumption) = I think, I guess, I assume
This is the most common usage of -겠- in casual and everyday conversation in Korean. You can use -겠- to show your opinion or assumption about something or what will happen, but you also give a nuance that you are somewhat careful with your opinion.
Ex)
아프겠어요.
= That must hurt.
Ex)
이게 좋겠어요.
= I think this will be good.
Ex)
늦겠어요.
= (I think) You’ll be late.
** When you want to express your assumption or ask someone else’s opinion about a possibility or a capability, you can use -겠-.
Ex)
혼자서도 되겠어요?
= Do you think you could handle it on your own?
저도 들어가겠네요.
= Even I would (be able to) fit in.
4. -겠- used in fixed expressions
In addition to the usages above, -겠- is also commonly used in some fixed expressions.
Ex)
알겠습니다.
= I got it. I understand.
Ex)
모르겠어요.
= I don’t get it. I don’t know. I am not sure.
Ex)
힘들어 죽겠어요.
= I’m so tired. This is so tough.
