Etymology: "Verifiability" is built in English from "verify" and the suffix "-ability," so its history runs through the word that gives it its core meaning. "Verify" came into English from Middle French "verifier," which descended from Late Latin "verificare," meaning to make true or to prove, from Latin "verus" ("true") and "facere" ("to make"). The English suffix "-ability" traces back through Middle French "-abilité" to Latin "-abilitas," itself formed from the adjective-forming "-abilis," the source of the English "-able." The suffix is a good example of how English stacks borrowed parts. "-able" and "-ability" together turn a verb into a noun describing the capacity for the action, so "verifiable" means able to be verified, and "verifiability" names the quality of being verifiable. Because the suffix attaches freely to many verbs, speakers can form new nouns like this one whenever a need arises, and "verifiability" became especially useful in philosophy and law, where it describes whether a claim can be checked against evidence.
