慣用句 (かんようく): idioms
慣用表現 (かんようひょうげん): idiomatic expressions
So like any language, Japanese has a whole set of idiomatic expressions to learn. These are often spoken, but also written as well. Some are super common, while others may not be.
Here are some common ones:
𝗘𝘅.𝟭
気をつけて (きをつけて): be careful
気にいる (きにいる): to like/pleased with
気になる (きになる): to become interested in
気が付く(きがつく): to notice/realize
𝗘𝘅.𝟮
耳をする (みみをする): hear by chance
目をする (めをする): see by chance
𝗘𝘅.𝟯
顔を出す (かおをだす): make an appearance, show up
頭が来る (あたまがくる): get on one’s nerves
𝗘𝘅.𝟰
心を込めて (こころをこめて): with all one’s heart
愛を込めて (あいをこめて): with love
The 2000 Essential Vocabulary For JLPT N3 has a nice list of them, and the Power Drill N3 Vocab also tests you on it (like the picture above).
Knowing these idioms can just add another level of understanding to your comprehension (same as onomatopoeias). Some of them are phrases you hear quite often in everyday life, so you’ll start to notice them often once you learn them.
