Etymology: In Latin, "insanitas" is built from "insanus," meaning "unsound" or "unhealthy," and the root idea is health. The prefix "in-" negates "sanus," which described a body or mind in good working order. Madness was thus understood as a failure of soundness, not as a separate condition. The ending "-itas" is a common Latin suffix that turns an adjective into an abstract noun, as in "felicitas" from "felix" (happy) or "bonitas" from "bonus" (good). The negated form "insanitas" therefore names the state of being "insanus." Its positive counterpart, "sanitas," meaning health or soundness, gave English "sanity."
