ignoramus

An ignoramus is a person who knows very little about something, or who seems generally uneducated or unaware. It is an old-fashioned, insulting word, so it does more than point out a lack of knowledge; it also shows contempt. You might hear it in a story, in a sharp argument, or in a mocking description of someone who speaks with confidence without really understanding the subject. The word comes from Latin, meaning "we do not know," but in everyday English it refers to the person, not the idea.

The word ignoramus comes from Latin and originally meant "we do not know." It was once used as a legal term on bills of indictment when a grand jury decided there was not enough evidence to proceed. Over time, the meaning moved away from the courtroom and settled into everyday English as a label for a person who is ignorant or poorly informed. A 17th-century play helped make the word more familiar by using it as the name of a foolish, pompous character.

An ignoramus is not just someone who lacks a fact or two. The word usually suggests a person who seems plainly ignorant, foolish, or unaware, and it is almost always insulting. In many cases, the person may speak confidently about something they do not understand, which is why the term often sounds mocking. Still, that extra sense of arrogance is common, not required. At its core, the word means an ignorant person.

You are more likely to see the term in literature, historical writing, or strongly worded commentary than in careful modern speech. It is the sort of word a narrator might use to paint someone as a fool, or that an angry speaker might throw at a person they think is badly informed. For example, a character in a novel might call a boastful man an ignoramus after he makes obvious mistakes about history or science. Everyone is ignorant about some things, but ignoramus turns that idea into a harsh personal label.
