How to say "affected" in Japanese

Choosing the right word
  • きざJLPT N1approx.Common
    na-adjective, nounCovers the 'affected' sense meaning pretentious or putting on airs, with a disapproving, colloquial nuance. Typical of casual criticism of someone's manner of speaking or acting as smug and self-important.
    彼かれらは彼かれのきざな話し方はなしかたを笑わらった。↗
    They laughed at the affectations in his speech.
  • 不自然ふしぜんCommon
    na-adjective, nounCovers 'affected' in the sense of artificial or strained, describing behavior or manner that does not come across as natural. Often the more neutral way to express this; the pretentious nuance is secondary to its basic meaning 'unnatural'.
    我々われわれ二人ふたりがここにいるのは不自然ふしぜんだ。↗
    The two of us don't belong here.

For the 'affected' meaning pretentious or showy, use 「きざ」; for behavior or manner that seems unnatural or strained, use 不自然 — the latter is usually the safer, more neutral choice.
