The word “Agelast” originates from the Greek language, specifically from the Greek word “ἀγέλαστος” (agelastos), which means “unlaughing” or “not easily amused.” It is derived from the combination of “ἀ-” (a-), a prefix denoting negation, and “γέλαστος” (gelastos), which means “laughable” or “amusing.” “Agelast” is used in English to describe a person who rarely or never laughs, typically due to a lack of humor or a stern disposition.
