Etymology: "Sclerotics" is the plural of "sclerotic", a noun for the tough, white outer coat of the eye, which is more formally called the sclera. The name comes from the Greek "skleros", meaning hard, which is also the root of words like "sclerosis" and "scleroderma", all describing hardened tissue. The adjective "sclerotic" is built from "scler(a)", the combining form of "sclera", plus the suffix "-otic", which English took from Latin "-oticus" via French "-otique". That suffix is used to form adjectives meaning "relating to" something, so "sclerotic" literally means "relating to the sclera." The noun use arose by ellipsis, with the word standing alone for the membrane itself.
