Etymology

First attested in 1425–1475, in Middle English; from Middle English illiterat(e) (“uneducated, ignorant of Latin”), borrowed from Latin illīterātus, illitterātus (“unlearned, ignorant”), itself from in- (“un-”) + līterātus, litterātus (“furnished with letters”) (see -ate (adjective-forming suffix)), from lītera, littera (“letter, character”). The noun was derived from the adjective by substantivization, see -ate (noun-forming suffix).
