Etymology : First known use is in the 14th century. Ignorant shares a root with the word ignore, one of those etymological connections which appear obvious once they are pointed out, yet remained overlooked by most. Both words come from the Latin ignorare (“to ignore, be ignorant of”). There are several meanings of ignorant, all of which are concerned with a lack of knowledge in some sense; some of these are more insulting than others, and care should be exercised before applying this word to people who you do not wish to offend. Saying “They were ignorant of most of the laws of physics” means that the people in question did not have a specific body of learning. Saying “You are an ignorant person” is possibly describing someone as primitive, crude, or uncivilized.
