Etymology

It is partly borrowed from Anglo-Norman affirmatif and partly borrowed from Late Latin affirmātīvus (“affirmative”),[2][3][4][5] and late Middle English also had the form affirmatyff.[6] The French word is recorded from the 13th century,[2][7] and the Anglo-Norman affermatif from 1292.[8] The Latin adjective was used by grammarians from the 4th century and in logic from the 5th or 6th.[2] It is formed from affirmātus, the past participle of affirmō (“to make steady, strengthen; confirm”), and the suffix -īvus.[3][2][7] The verb is from ad- (“to”) and firmō (“to strengthen, make firm”), from firmus (“strong”).[7]

Earliest recorded meaning

Asserting that something is so; expressing a positive answer: about 1449, in Reginald Pecock's Repressor.[2] Etymonline dates the sense "answering yes" to the mid-15th century and traces it to the language of logic.[7]

Semantic evolution

The noun, a statement or proposition that affirms, is recorded from about 1450,[2] or the early 15th century according to Etymonline,[7] and the affirmative, the side of a question that assents, and the phrase in the affirmative both from about 1460.[2] The technical use in logic, of a proposition that asserts a predicate of its subject, is recorded from 1532, in Thomas More.[2] Several senses have died out: "strengthening, giving emphasis" (about 1504 to 1580), "assertive, dogmatic" (1650 to 1773) and, in mathematics, "positive, greater than zero" (about 1665 to 1885).[2] Johnson (1755) defined the adjective as "that which affirms, opposed to negative".[9] From 1702 it could mean confirming, as of a court judgment that upholds a lower court's decision, and since 1862, in Emerson, positive or encouraging.[2] The use as a bare "yes" began in American military signalling, recorded from 1803,[2] and spread with radio communication: that's affirmative is recorded from 1956 and the noun in this sense from 1961.[2][3] The verb, to carry a motion or reply yes, is recorded from 1775.[2] Affirmative action is attested in American English from 1935 for the reinstatement of fired union members, and in its racial sense from 1961; by the late 1970s it had come to mean active measures such as hiring quotas.[7]
