(こい)()ちる

こいにおちる
expression
to fall in love
emotionrelationship
1. to fall in love
To suddenly or unexpectedly develop romantic feelings for someone. A direct parallel to the English expression 'fall in love,' conveying that love is something one falls into rather than chooses.
彼女(かのじょ)(こい)()ちた。
I fell in love with her.
一目(ひとめ)(こい)()ちてしまった。
I fell in love at first sight.
The two met at university and quickly fell in love.

A common expression combining (こい) (romantic love) + (into) + ()ちる (to fall). Like the English "fall in love," it implies that love happens suddenly or irresistibly, not through deliberate choice.

Common patterns

  • (ひと)(こい)()ちる: to fall in love with someone
  • 一目(ひとめ)(こい)()ちる: to fall in love at first sight
  • (こい)()ちてしまう: to end up falling in love (with a nuance of it being beyond one's control)

Similar words

  • (こい)する: to be in love, to have a crush — more neutral and everyday; doesn't carry the "falling" metaphor
  • ()れる: to fall for, to be smitten — more colloquial and direct
  • ()なる: to come to like — broader and milder; can apply to non-romantic contexts too

Usage

Common in romantic fiction, song lyrics, and everyday conversation. Slightly more dramatic or literary than ()なる, emphasizing the uncontrollable nature of romantic attraction.
