Did you know?
- While 暑い is used for the weather, if you want to say a person is 'hot' in a sexual or attractive sense, you would not use either form of 'atsui'. Instead, you might use words like かっこいい for handsome or セクシー for sexy.
- In Japanese, 'hot' as in 'spicy' is expressed by the word 辛い (karai), so you should never use 暑い or 熱い to describe spicy food.
- While 暑い refers to the weather, the phrase 熱い can also describe someone with a passionate or fiery personality.
