means The local figure, real or stock, whose foolishness (or blunt truth-telling) made them the butt of every joke in a small community.

from A straightforward compound from 'village' (via French and Latin 'villa,' a country house/estate, which grew to mean the settlement around it) and 'idiot.' That second word has the sharper backstory: Greek 'idiotes' simply meant a private person — someone outside public office, not a fool, just an ordinary civilian minding their own business. Over centuries in Latin and then English, 'idiot' narrowed and soured, coming to mean someone ignorant or mentally deficient. 'Village idiot' crystallized as a stock phrase for the supposed designated fool of a small, close-knit community — half social history, half cruel cliché.
