agonist

Etymology

It is borrowed from Late Latin agōnista (“combatant, competitor”),^{[2][3][4][5][1]} from Ancient Greek ἀγωνιστής (agōnistḗs, “combatant, competitor, champion”),^[2][3][4][1] from ἀγωνίζομαι (agōnízomai, “to contend, fight”) and the suffix -ιστής (-istḗs),^[2][4] ultimately from ἀγών (agṓn, “gathering, assembly, contest”).^[3][6][7] In post-classical Latin, from the 4th century, the word also meant a person engaged in a spiritual struggle.^[2] Etymonline derives the Greek noun from ἀγωνία (agōnía, “a struggle for victory”).^[8] The Merriam-Webster Unabridged takes the sense of a muscle as borrowed from German Agonist,^[4] and the OED takes the sense of a writer of an agony column as partly formed in English, from agony and -ist.^[2] The OED compares agonistes and the earlier antagonist.^[2]

Earliest recorded meaning

Apparently a religious scholar: 1573, in T. Twyne's translation of H. Llwyd's Breuiary of Britayne, a rare sense now obsolete.^[2] The sense of a competitor in the public games follows in 1623, in Cockeram's English Dictionarie;^[2] Random House dates the word to 1620–1630,^[5][9] the Shorter Oxford to the early 17th century,^[10] the Merriam-Webster Unabridged to 1658,^[4] and Etymonline to 1876.^[8]

Semantic evolution

In the 17th and 18th centuries the word was a dictionary term for a competitor in the games of ancient Greece and Rome;^[2][10] Johnson (1755) defined it as "a contender for prizes".^[2][11][10] From 1687 it was used of anyone engaged in a dispute or struggle, and of the main figure in a drama or course of events, a protagonist;^[2] Etymonline finds it in writings on Greek drama from 1876 for the hero attacked by an antagonist.^[8] Smyth's Sailor's Word-Book (1867) glosses it as a champion or prize-fighter.^[12] The scientific senses pair it with antagonist: in physiology, from 1896, a muscle that contracts to produce a movement, and in pharmacology, from 1955, a drug or other substance that combines with a receptor and produces an effect.^[2][10] In 1914 The Times used it for a writer of an agony column, a sense now somewhat dated.^[2]
