Questions & Answers about jigeum deowoseo eeokeoneul kyeoyo.
What does the ending -서 in 더워서 do here?
It’s the connective -아서/어서, which links two clauses with a cause-and-result meaning: “because/since/so.” In this sentence, it means “because it’s hot (now), [I] turn on the AC.” It’s showing the reason for the second clause.
Why is it 더워서 and not 덥어서?
The adjective 덥다 (to be hot, weather/ambient) is a ㅂ-irregular. When a vowel-initial ending like -아서/어서 is attached, the ㅂ changes to 우, and then contracts:
- 덥다 → 더우 + 어서 → 더워서 Related forms:
- Present polite: 더워요
- Past: 더웠어요
- Conditional: 더우면
- Reason with -(으)니까: 더우니까
Can I use 뜨거워서 instead of 더워서?
Generally no.
- 덥다 is used for weather/air or how a person feels due to ambient heat (It’s hot/the room is hot/I’m hot).
- 뜨겁다 is for things that are hot to the touch (hot water, hot plate) or body temperature in a medical sense (e.g., 몸이 뜨거워요 for “I have a fever”). So “Because it’s hot now” is naturally 지금 더워서, not 지금 뜨거워서.
Why is it 에어컨을 with 을? Could it be 에어컨이?
