Etymology: "Halfwitted" is a plain compound: "half" joined to "witted," the adjective formed from "wit" in its older sense of mental capacity or understanding. Half-witted therefore means having only half the wits a person should have, a picture of someone whose mind falls short of what it ought to be. The "wit" in this sense is the Old English "wit," meaning intellect or knowing, which is the same root that gives "wisdom" and "wit" in the sense of cleverness, so the word is built from the same material as those two. The "half" in the compound is not meant as an exact measurement. It works as an intensifier of deficiency, the way "half-baked" or "half-hearted" describe something incomplete or lacking in conviction. Because the compound is transparent, English speakers can parse it without any special knowledge, and its meaning has stayed close to its literal construction.
