Synonym Usage

Ignorant, illiterate, unlettered, uneducated mean lacking in knowledge or in training. Ignorant may mean knowing little or nothing, or it may mean uninformed about a particular subject: An ignorant person can be dangerous. I confess I'm ignorant of mathematics. Illiterate originally meant lacking a knowledge of literature or similar learning, but is most often applied now to one unable to read or write: necessary training for illiterate soldiers. Unlettered emphasizes the idea of being without knowledge of literature: unlettered though highly trained in science. Uneducated refers especially to lack of schooling or to lack of access to a body of knowledge equivalent to that learned in schools: uneducated but highly intelligent. None of these words mean "lacking in intelligence."

Etymology

Origin of ignorant

First recorded in 1325–75; Middle English ignora(u)nt, from Latin ignōrant-, stem of ignōrāns “not knowing,” present participle of ignōrāre “to not know”; see ignore ( def. ), -ant ( def. )

Explanation

If you make an ignorant comment, your listeners might laugh at you, might get mad at you, or they might patiently instruct you in the ways that you are uninformed. People can be generally ignorant, meaning that they are uneducated and lacking in sophistication. Or people can be ignorant of specific types of information. In fact, we all are. For example, most of us are ignorant of the particulars of nuclear physics and ignorant about what it takes to be an astronaut. Sometimes people are also labeled ignorant if they are rude, inconsiderate, or narrow-minded.
