affirm

Etymology

It is inherited from Middle English affermen, also affirmen,^[2][3][4] borrowed from Anglo-Norman afermer, also affermer, and Old French afermer,^{[5][3][6][7][4]} from Latin affirmō (“to strengthen, confirm, assert”).^[5][2][7][3] The OED treats the English word as partly a direct borrowing from Latin,^[5] and in the 16th century the spelling was remodelled on the Latin in both languages, giving affirmer and English affirm.^[8][2][3] The Latin verb is formed of ad- (“to”) and firmō (“to make firm, strengthen”),^[5][2][8] from firmus (“strong, firm”),^[2][7][9] from a suffixed form of Proto-Indo-European *dher- (“to hold firmly, support”).^[2][7] In Old French the verb meant to make something firm from the 10th century and to assert that something is true from 1119;^[5] the Anglo-Norman verb is recorded from 1113–19, meaning to strengthen, secure or establish.^[6] Compare Spanish afirmar, Portuguese afirmar and Italian affermare.^[5]

Earliest recorded meaning

In law, to uphold or ratify a judgment, covenant or law: before 1325, in the Statutes of the Realm.^[5] Barnhart dates affermen, "make firm", to probably before 1300,^[8] and Etymonline gives "to decide upon" from about 1300.^[2]

Semantic evolution

The Middle English verb kept the Latin senses "to make firm, establish" (until the 17th century)^[5][10] and "to confirm a statement".^[5][10] The sense "to state positively, assert as true" arose in the late 14th century, first in the Wycliffite Bible and in Chaucer.^[5][2] From the early 15th century it was also used of swearing or declaring formally, and in law it came to mean making a solemn declaration without an oath.^[5][2] Logic (1551) and grammar (before 1586) took it up for stating a proposition as true or giving a positive meaning.^[5] Johnson (1755) recorded both the legal sense of ratifying a former law or judgment, as opposed to reversing it, and the sense of declaring confidently, as opposed to denying.^[11] A use that began in the United States, asserting the value of life through an uplifting experience, is recorded from 1899.^[5] Affirm was also clipped from affirmative as a radio word for "yes" in 1960.^[5]
