How to say "slender" in Japanese

Choosing the right word
  • 細いほそいJLPT N5approx.Common
    i-adjectiveThe everyday adjective for anything physically thin or slender — a waist, fingers, branches, a thread. It describes the object itself and is the default choice when 'slender' simply means 'thin'.
    彼かれは太ふとっているくせに声こえは細ほそい。↗
    His voice is thin even though he is fat.
  • na-adjectiveThe loanword from English 'slender', used of a person's figure: a tall, slender woman. It describes an attractively slim body shape rather than the thinness of objects.
  • スマートJLPT N2approx.Common
    na-adjectiveA loanword that in Japanese means 'slim': it describes a person with a trim, slender figure. Note that it does not mean English 'smart' in the sense of intelligent.
    あんなドレスが着きられたらいいんだけど。もっとスマートにならなくちゃ。↗
    I'd love to be able to wear a dress like that. But I'll have to lose some weight first.
  • 細身ほそみCommon
    no-adjectiveA noun meaning a slender figure or build. Use it when you want to name the body type itself — a person of slender build — rather than describe it with an adjective.

Use 「細い」 for things or body parts that are physically thin, 「スレンダー」 and 「スマート」 for a person's slim figure, and 細身 when naming a slender build as a noun.
