How to say "gradual" in Japanese

Choosing the right word
  • なだらかJLPT N2approx.
    na-adjectiveIts core sense is 'gently sloping'; as 'gradual' it describes a smooth, unhurried change — gentle rather than steep or abrupt — not change organized into deliberate stages.
    道みちはなだらかな上あがりになっていた。↗
    The road climbed gradually.
  • 漸進的ぜんしんてき
    na-adjectiveCovers 'gradual' as slow, steady advance toward a goal, proceeding little by little. A less common word; for most purposes 段階的 is the more useful choice.
  • 漸次的ぜんじてき
    na-adjectiveCovers 'gradual' in the sense of a change proceeding little by little, with an added nuance of slowness. It sits close to 漸進的 in meaning, and both are less common choices.
  • なし崩し的なしくずしてき
    na-adjectiveRestricted to a negative 'gradual': something being destroyed, dismantled, or worn away bit by bit, often before anyone quite notices. It is not a general word for gradual change.
  • 段階的だんかいてき
    na-adjectiveDescribes change carried out in distinct stages or steps — incremental, step-by-step progress. Among these words it is the broadest and most dependable way to say 'gradual' for planned, phased change.

Use 段階的 for change in deliberate stages, 漸進的 and 漸次的 for slow, little-by-little advance, 「なだらか」 for gentle, unhurried change, and 「なし崩し的」 only for things gradually worn away or dismantled.
