How to say "fleeting" in Japanese

Choosing the right word
  • はかないJLPT N1approx.Common
    i-adjectiveThe default for fleeting in the sense of transient: things such as a life, a dream or a love that pass quickly and cannot last, often with a wistful feel. Usually written in kana alone.
    人生じんせいは儚はかないよ、と人ひとは言ゆう。↗
    People say that life is short.
  • チラリCommon
    adverb (with と)Fleeting in the sense of a glimpse or glance: something caught by the eye for an instant. A mimetic word for that brief flash of seeing, not for transient things — use はかない there.
    彼かれは書類しょるいをちらりと見みた。↗
    He took a glance at the papers.
  • 淡いあわいCommon
    i-adjectiveChiefly means light, faint or pale, of colors, light and faintly held feelings. Its 'fleeting' sense is that faintness; for fleeting in the sense of transience, はかない is the word you want.
    本気ほんきで似合にあうと思おもっていたらしいシャツは辞退じたいし、淡あわいブルーのポロシャツをいただくことにした。↗
    The shirt she apparently seriously thought suited me I turned down and decided to accept a light blue polo shirt.

Use 「はかない」 for the general sense of transient, short-lived things; 「チラリ」 only for a fleeting glimpse or glance; 「淡い」 chiefly means faint or pale, its 'fleeting' nuance being a slight, faintly held feeling.
