argumentative

Etymology

From Late Middle English argumentatif (“syllogistic, sophistic”), from Old French argumentatif, argumentative (modern French argumentatif (“argumentative”)) and Medieval Latin, Late Latin argūmentātīvus, from Latin argūmentātor + -īvus (suffix forming adjectives). Argūmentātor is the second-person singular future active imperative of argūmentor (“to prove, reason; to adduce something as an argument or proof; to conclude”), from argūmentum (“argument for a position; evidence, proof”) (from arguō (“to show; to prove; to assert, declare; to make clear”) (possibly ultimately from Proto-Indo-European *h₂erǵ- (“white, argent; glittering”)) + -mentum (suffix indicating the result of something)) + -or.
