Earliest recorded meaning
It is a grammarians' word: Diomedes, in the second half of the 4th century AD, speaks of an affirmative kind of verb.[3][4]
Semantic evolution
Medieval writers used it of what confirms or permits, and above all in logic and music theory for what affirms, as opposed to negative.[5] As a feminine noun it named an affirmative proposition: an English logic text of before 1250 divides statements into affirmativa and negativa.[6]
Eriugena calls the part of theology that predicates everything of the divine essence affirmativa.[6] English affirmative came through Old French in the mid-15th century, from its use in logic.[2]
