κῠνῐκός (kunikós) m (feminine κῠνῐκή, neuter κῠνῐκόν); first/second declension[1]
Etymology
It is formed from Ancient Greek κύων (kúōn, “dog”) + -ικός (-ikós).[1][2][3] The noun κύων (kúōn) goes back to Proto-Indo-European *ḱwṓ (“dog”), genitive *ḱun-ós, which the Greek genitive κυνός (kunós) continues.[4][1]
The Cynic philosophers, the followers of Antisthenes, were said to be named after the gymnasium of Κυνόσαργες (Kunósarges) where he taught, or after their dog-like way of life, and Diogenes the Cynic himself is quoted explaining it the second way.[2][5]
Earliest recorded meaning
It first appears as a variant reading in Xenophon's Cyropaedia, meaning “dog-like”.[2]
Semantic evolution
The plain sense “of a dog, dog-like” stayed in use: Plutarch speaks of the dog-like and bestial part of the appetites, the Septuagint calls a man currish, and medical writers name a one-sided facial paralysis the “dog spasm”.[2][6] Polyaenus uses it for the heat of the dog days.[2][6]
From the 4th century BC it was the name of the Cynic philosophers: Menander mentions “Crates the Cynic”, and later writers speak of the Cynic sect, discipline and philosophy.[2] Their blunt outspokenness, Cynic παρρησία (parrhēsía), became proverbial, and Plutarch uses the neuter for a Cynic-like frankness of speech.[2][7]
It passed into Latin cynicus, from which come English cynic (1550s) and French cynique.[8][5][3] Modern Greek κυνικός (kynikós) is a learned word: it keeps the ancient philosophical sense and has taken the sense “cynical” from French.[9][3]
