Confusing Words

fictitious vs fictional

Fictitious and fictional both relate to things that are not real, but they have different connotations.

  • fictitious — Fictitious carries a stronger sense of deception or falsehood, often implying that something has been deliberately created to mislead: 'The company submitted fictitious expense claims to avoid paying tax.'
  • fictional — Fictional simply means invented or imaginary, and is most commonly used for stories, characters, and narrative creations: 'The events of the novel are entirely fictional.'

Memory rule: A useful rule: use fictional for characters, worlds, and stories that are invented but not deceptive. Use fictitious when something has been fabricated with the intention to mislead or deceive. If you can replace the word with 'made up to deceive', use fictitious.
