What it means

鈍い means dull or blunt, describing something not sharp or a person slow to perceive. It covers physical dullness as well as cognitive or perceptual sluggishness, and can describe dull pain or dull responses.

Main meanings

  • Physical dullness: a blade or edge that is not sharp.
  • Perceptual slowness: reduced senses or slow understanding; common collocations include 反応が鈍い and 頭が鈍い.
  • Dull pain or ache: a non-sharp, lingering sensation.
  • Muted brightness or sound: a color or noise that feels dull or unremarkable.

How to use it

鈍い is an i-adjective used to describe dullness in objects or people's perception, or slow to react; attaches to nouns directly (鈍い刃) and to predicates (edge が 鈍い, person が 鈍い). It is used in casual and neutral contexts; for people, prefer specific phrases like 頭が鈍い or 感覚が鈍い to avoid bluntness.
