Fun Fact
Linguists love derivation because it lets them trace how words evolve—from one language to another, and one meaning to another. Some derivations are direct (photo → photos → light), but others take surprising turns. The word salary comes from the Latin salarium, which referred to money paid to Roman soldiers to buy salt. This makes derivation a vital tool for not just grammar nerds, but also historians and anthropologists.
(adjective) Devoid of intelligence, substance, or meaningful content; empty in a way that is made worse by the appearance of fullness.
The panel discussion was so vacuous — four articulate people saying nothing of substance for ninety minutes — that the audience left feeling vaguely cheated by their own attention.
Vacuous derives from the Latin vacuus, meaning “empty” or “void,” rooted in vacare — “to be empty” or “to be free.” The same root gives us vacuum, vacant, vacation — all words built around the idea of emptiness or absence. It entered English in the 17th century, initially used in scientific contexts to describe a literal vacuum before acquiring its cutting figurative sense of a mind or expression that contains nothing worth engaging with.
