Etymology

The word "fatuous" comes from the Latin fatuus, meaning "foolish" or "silly." The suffix -ous is an English adjectival ending derived from Latin -osus, indicating "full of" or "having the quality of." Thus, "fatuous" literally means "full of foolishness." The term has retained its pejorative connotation, often describing behavior or remarks that are not just silly but also annoyingly devoid of sense.
