What does fatuous mean?
Fatuous is an adjective describing something foolish, silly, or pointless — especially in a way that betrays a smug or complacent lack of awareness. A fatuous remark is not merely mistaken; it is empty-headed, and often delivered with an air of self-satisfaction that makes it all the more grating. The word appears frequently in critical and formal contexts: reviewers use it to dismiss weak arguments, journalists to puncture glib political statements, and commentators to describe vapid behaviour. Its connotation is sharply disapproving, carrying an implication of contempt for thoughtlessness rather than mere amusement at it. Derived from the Latin fatuus, meaning foolish, it shares its origins with infatuate and the noun fatuity. For writers seeking a precise, cutting term for silliness of the self-satisfied variety, fatuous is an unusually effective choice — more damning than 'silly' and more specific than 'stupid.'
adjectiveSilly, pointless, or lacking in intelligence or serious purpose; foolish in a self-satisfied or complacent way.
- Foolish, silly, or devoid of intelligence; completely lacking good sense.
- Pointless or meaningless in a way that suggests complacent unawareness of the fact; unreal or vacuous.
"His fatuous remark about the unemployed simply not wanting jobs revealed how out of touch he was."
"She dismissed his fatuous plan to solve the budget crisis by 'just printing more money.'"
"He wore a fatuous grin throughout the ceremony, evidently delighted with himself."
Fatuous comes from the Latin fatuus — the same root that gives us "infatuated," so the fool and the lovesick really do share an ancestry.

Etymology of fatuous
Fatuous derives from the Latin adjective fatuus, meaning foolish, silly, or insipid, which entered English in the early seventeenth century. The same Latin root produced the English verbs and nouns infatuate and infatuation, originally conveying the idea of being made foolish, as lovers were thought to be. The related noun fatuity, meaning foolishness or stupidity, came from the same source. Cognates appear across the Romance languages, such as French 'fatu' and Italian 'fatuo', both carrying the same sense of emptiness or silliness.
