How to say "differentiate" in Japanese

Choosing the right word
  • 見分けるみわけるCommon
    ichidan verb, transitive verbThe default choice for 'differentiate' in the sense of telling things apart — distinguishing or recognizing differences between similar items by looking or observing. Use this when you simply mean 'to tell apart'.
    彼かれと彼かれの兄あにを見分みわけるのは簡単かんたんだ。↗
    It is easy to tell him from his brother.
  • 住み分けるすみわける
    ichidan verb, transitive verbCovers 'differentiate' only in the sense of different groups or things segregating and settling into separate niches while coexisting. It is a less common word; for telling items apart, this is not the word you want.
  • 聞き分けるききわける
    ichidan verb, transitive verbRestricted to differentiating by hearing: recognizing or telling apart voices, sounds, and the like. For 'differentiate' applied to sounds or voices this fits, but it is wrong for visual or general distinguishing.
    小鳥ことりの声こえを聞き分ききわけることが出来できますか。↗
    Can you tell one bird from another by hearing them?
  • 特色づけるとくしょくづける
    ichidan verb, transitive verbMeans to differentiate in the sense of marking something out or characterizing it — giving something its distinctive features. It is a less common, somewhat formal choice and is not used for simply telling things apart.

Use 「見分ける」 for telling things apart visually or by observation, 「聞き分ける」 only for sounds and voices, 「住み分ける」 for groups coexisting separately, and 「特色づける」 for characterizing something distinctively.
