cynic

Origin

From Middle English cynike, cynicke, from Middle French cynique, from Latin cynicus, from Ancient Greek κυνικός (kunikós), originally derived from the portico in Athens called Κυνόσαργες (Kunósarges), the earliest home of the Cynic school, later reinterpreted as being derived from κύων (kúōn, “dog”), in a contemptuous allusion to the uncouth and aggressive manners adopted by the members of the school.
