-면 is a conditional ending. It means if or when, depending on context.
So 더우면 means if it is hot or when it is hot.
In this sentence, it sets up the condition first:
- 더우면 = if/when it’s hot
- 선풍기를 틀어요 = turn on the fan
This comes from the dictionary form 덥다, meaning to be hot.
덥다 is a ㅂ-irregular adjective. When an ending beginning with a vowel is added, the ㅂ changes to 우.
So:
- 덥다 → stem 덥-
- 덥 + -면
- ㅂ changes to 우
- 더우면
This same pattern appears in other words too:
- 춥다 → 추우면
- 어렵다 → 어려우면
So 더우면 is the correct irregular form.
