Ex

(104). A Latin preposition or prefix, Gr. ἐξ or ἐκ, signifying out of, out, proceeding from. Hence, in composition, it signifies sometimes out of, as in exhale, exclude; sometimes off, from, or out, as in exscind; sometimes beyond, as in excess, exceed, excel. In some words, it intensifies the meaning; in others, it has little effect on the signification. Ex, prefixed to names of office, denotes that a person has held that office, but has resigned it, or been left out, or dismissed; as, ex-chancellor, ex-president, and the like.
