Etymology: Disprovability is a modern formation: the English verb "disprove" with the suffix "-ability" attached. That suffix has a long pedigree, passing into English through Middle French from Latin "-abilitas", which was built on "-bilis" (and, before that, "-ābilis"), a Latin adjective ending meaning "able to be" or "capable of being" something. Its earliest ancestors reach back through Proto-Italic into Proto-Indo-European, but the working parts that matter are these: "-able" comes from Latin, and "-ability" is the noun that turns "capable of being X" into "the quality of being capable of being X." So "disprovability" literally means "the quality of being capable of being disproved." Its everyday sense is the one philosophers have leaned on: a claim is worth taking seriously only if some observation could show it wrong. The word therefore names a property of statements rather than of the world, and it gives a precise label to what the English verb "disprove" already implied.
