antagonist

Etymology

It is borrowed from Late Latin antagōnista (“opponent”), used by Jerome in the 4th century,^[2][3][4] and partly borrowed from French antagoniste,^[5][3][6][7] from Ancient Greek ἀνταγωνιστής (antagōnistḗs, “opponent, rival”),^[2][5][4][8] an agent noun from ἀνταγωνίζομαι (antagōnízomai, “to struggle against, vie with”),^[2][5][9] formed from ἀντί (antí, “against”) and ἀγωνίζομαι (agōnízomai, “to contend for a prize”),^[5][8] from ἀγών (agṓn, “contest, struggle”), the source of agony.^[5][9] In the 16th century the Latin noun was also used of a counteracting muscle.^[2] The word spread through Europe at about the same time: German Antagonist is recorded in 1562, the French noun by 1570, Spanish antagonista in 1626 and Italian antagonista in 1631.^[2]

Earliest recorded meaning

A person who holds the opposing view in a controversy: 1555, in T. Cole's account of the troubles at Frankfurt.^[2] Merriam-Webster dates the word to 1575 and Etymonline to the 1590s.^[4][5]

Semantic evolution

Etymonline describes the word as first used of opponents in battle or sport and extended in the 1620s to any field;^[5] in the OED both senses are recorded by 1585.^[2] Johnson (1755) defined it as "one who contends with another; an opponent", adding that it generally implies a personal and particular opposition.^[10] Anatomy took it up for a muscle that works against another (1615), and pharmacology for a drug or substance that blocks the action of another (1842).^[2] Since 1647 it has also been used of an impersonal opposing force.^[2] In literary criticism it was first used of either speaker in the formal debate of an ancient Greek play (1887), and since 1914 of the chief opponent of the protagonist in a play or story.^[2] An adjective use, "acting in opposition", is recorded from 1591.^[2]
