Confusing Words

discreet vs discrete

These two adjectives are among the most commonly confused words in formal English, largely because they are pronounced identically yet have entirely different meanings.

  • discreet — Discreet means careful and circumspect in behaviour or speech, particularly in situations that require avoiding unnecessary attention or not revealing sensitive information. A discreet enquiry is one made quietly, without drawing attention.
  • discrete — Discrete means individually separate and distinct, forming a self-contained unit that is not connected to or confused with other units. Discrete categories do not overlap; discrete events are individually bounded.

Memory rule: A reliable guide: discreet is about behaviour (being careful and tactful), while discrete is about separation (being individually distinct). Remember: discreet ends in ‘creet’ — be discreet, and keep things ‘neat’; discrete ends in ‘ete’ — think of each ‘e’ as a separate, distinct item.
