夏休み
なつやすみ · natsuyasumi · JLPT N5 · noun
vacation
🌻🏖️ 夏休み = 夏 summer (natsu) + 休み rest (yasumi)
夏 (natsu) means summer and 休み (yasumi) is the noun form of 休む, to rest. The same pattern gives 冬休み (fuyuyasumi, winter break) and 昼休み (hiruyasumi, lunch break), so learning yasumi once unlocks a whole family of break words.
