You’re watching the Korean evening news, and the forecaster says:
“내일은 비가 오겠습니다.” (It will rain tomorrow.)

Wait — does that mean the weathercaster is promising to make it rain? 😄

Not quite! To understand why, we need to look at what -겠습니다 really means.

1. What does -겠습니다 usually mean?

In English, it’s closest to “I will,” “I shall,” or “I promise to.”

While other future expressions simply describe a plan, -겠습니다 carries the weight of personal commitment. It tells the listener: “I’ve decided to do this, and I’m officially committing to it.”

So back to our weathercaster — they aren’t promising to control the weather! In formal broadcasts and news reports, -겠습니다 is used to deliver information with authority and confidence. It signals an official expectation, not a personal vow.

📺 On the news: “맑겠습니다.” → “It is officially expected to be sunny.”
☀️ With friends: “맑을 거예요.” → “I think it’ll be sunny!”

Same weather, different feel. In daily conversation, (으)ㄹ 거예요 sounds much more natural.

2. Super Simple Form (No “으” Needed!)

Here is the best part: -겠습니다 is very easy to use!

Unlike many Korean grammar points that require you to add -(으)- when there is a final consonant, -겠습니다 never changes. You just stick it directly to the end of any verb stem.

Verb TypeStemFinal FormEnglish Meaning
No Consonant가-가겠습니다I will go.
With Consonant먹-먹겠습니다I will eat.
‘ㄹ’ Consonant만들-만들겠습니다I will make.
Irregular ‘ㅂ’돕-돕겠습니다I will help.

⚠️ Common Mistake: Don’t say “먹으겠습니다” (X).
Even with a consonant, it’s always just -겠습니다! (O)

3. When should you use it?

Because -겠습니다 expresses firm will or intention, it fits naturally in formal or resolute situations:

  • At work: “I will check the report.” → 확인하겠습니다.
  • In class: “The lesson will begin now.” → 시작하겠습니다.
  • Making a resolution: “I will study harder!” → 열심히 하겠습니다.
  • Polite acknowledgment: “Understood.” → 알겠습니다.

4. How is it different from -(으)ㄹ게요 or -(으)ㄹ 거예요?

5. Remember: It’s usually about “ME”

Because it’s about intention, you mostly use it for your own actions (I/We).

  • ✅ 제가 하겠습니다. (I will do it.)
  • ❌ 친구가 하겠습니다. (My friend will do it.) — Use “갈 거예요” for others.

Note: Weathercasters use it for the weather in news reports (“비가 오겠습니다”), but in daily life, talk about the weather with “(으)ㄹ 거예요”!

6. Top 5 “Must-Know” Phrases

  1. 알겠습니다. (Got it! / I’ll keep that in mind.)
  2. 열심히 하겠습니다. (I’ll work hard / I’ll do my best.)
  3. 잘 먹겠습니다! (I will eat well — said before a meal.)
  4. 처음 뵙겠습니다. (Nice to meet you — literally: I see you for the first time.)
  5. 최선을 다하겠습니다. (I will do my best.)

      아주 잘 했어요. You did a great job! However, it is more natural to say ‘내일’까지’ 끝내겠습니다’ (I will finish it by tomorrow) or ‘내일 끝내겠습니다’ (I will finish it tomorrow). Also, in Korean, time words like 내일 (tomorrow), 오늘 (today), and 어제 (yesterday) don’t need a particle like ‘-에’. So instead of saying ‘내일에’, just use ‘내일’ on its own.
