Is it a burnt out or burned out light bulb?

Burnt and burned are two spellings of the same verb. The usage depends on the variant of English.

  • In British English, both “burned” and “burnt” are used for both the verb and adjective, but burnt-out light bulb is a bit more common.
  • In American English, “burned” is used as a verb, while “burned” and “burnt” are used interchangeably as adjectives. However, burned-out light bulb is more common in American English.
