How to say "deliberately" in Japanese

Choosing the right word
  • あえてJLPT N1approx.Common
    adverbCovers deliberately doing something needless, unexpected, or seemingly counterproductive — going against the natural course on purpose, often with a nuance of daring or defiance.
    あえて彼かれの意見いけんを支持しじした。↗
    I dared to support his opinion.
  • わざとJLPT N3approx.Common
    adverbThe usual word for deliberately doing something bad or annoying: acting with intent, as in doing something on purpose to provoke or inconvenience someone.
    そのピエロはわざと転ころんだ。↗
    The clown fell down on purpose.
  • じっくりJLPT N1approx.Common
    adverb (with と)A mimetic word meaning slowly, carefully, and thoroughly; 'deliberately' here describes unhurried, careful action, not intention. It is not the word for doing something on purpose.
    じっくり彼かれに耳みみを貸かす者ものはいない。↗
    No one stops to listen to him.
  • 好んでこのんでCommon
    adverbMeans by choice or by preference — doing something of one's own free will because one likes it. It matches 'deliberately' only loosely and is rarely the word you want.
    She likes to eat fresh raw vegetables.
  • わざわざJLPT N1approx.Common
    adverbIntentionally or on purpose, typically for something that takes special trouble or effort, often when the effort seems unnecessary or the result not worth it.

For intentional acts use 「わざと」 or 「わざわざ」; for choosing to do something unexpected or seemingly unwise use 「あえて」; 「じっくり」 means doing things slowly and carefully, and 「好んで」 means by preference.
