Confusing Words

bemuse vs confuse

These two verbs both describe a state of not understanding, but they differ in the nature and degree of that lack of understanding.

  • bemuse — Bemuse means to puzzle or bewilder someone in a mild or gentle way, often with a quality of surprise or absurdity. To be bemused is to be slightly mystified or perplexed, often with an element of amusement. It is generally used for situations that are puzzling but not distressing.
  • confuse — Confuse means to make something difficult to understand, or to cause someone to mix up distinct things. Confusion is more thoroughgoing than bemusement: it involves a genuine failure to understand or a mistaken identification of different things as the same.
  • perplex / amuse — perplex' confuse or puzzle someone, while 'amuse' entertain someone or make them laugh. Choose the word that matches the exact job you need it to do in the sentence.

Memory rule: A reliable guide: bemuse suggests mild, often mildly amusing puzzlement; confuse suggests a more thorough lack of understanding or a mistaken identification. An unusual claim might bemuse a reader; an unclear argument will confuse them. If the distinction between two things is genuinely difficult to draw, it is confusing; if the thing itself is merely strange, it is bemusing.
