- Synonyms Ignorant, Illiterate, Unlettered, Unlearned, uneducated. Ignorant is the most general of these words (as, he is an ignorant fellow), except where it is limited to some subject or point (as, ignorant of the ways of the world). Illiterate means not having read or studied, or, specifically, not able to read. The illiterate are presumably ignorant outside of their own work, but not necessarily so; the ignorant are necessarily illiterate. In modern times it is as reprehensible to be illiterate as to be ignorant. Unlettered is used sometimes for illiterate and sometimes for unlearned, with corresponding measures of blame. Unlearned —that is, not learned—is, like ignorant, either general or special: as, to be unlearned in theology; as learning is the privilege of few, it is not especially blameworthy to be even generally unlearned.
- n. A person who is untaught or uninformed; one who is unlettered or unskilled; an ignoramus.
