Common Synonyms for Crazy

Crazy vs. Insane

  • He had this crazy idea that he could learn to fly without any formal training.
  • It’s simply insane to go hiking in the wilderness without a map.

Crazy vs. Mad

  • He was so mad, ranting about the most trivial issues as if the world was ending.

  • She’s just crazy about that band, follows them to every concert.
  • The man’s lunatic ravings frightened the bystanders.

While ‘crazy‘ is colloquial and non-specific, ‘psychotic’ refers to a specific psychological state involving a disconnection from reality, such as delusions or hallucinations, and is a term used in a psychiatric context.
