Etymology

Origin of ignoramus

1570–80; < Latin ignōrāmus we ignore (1st person plural present indicative of ignōrāre to be ignorant of, ignore ); hence name of an ignorant lawyer in the play Ignoramus (1615) by the English playwright G. Ruggle, whence current sense

Explanation

If you've ever been afraid to speak up in class, you might be worried that you'll look like an ignoramus, or an uneducated, ignorant person. Calling someone an ignoramus is an insult — it's a colorful way to comment on a person's ignorance or stupidity. The word comes right from the Latin ignoramus, literally "we do not know," which was a legal term in the 16th century that could be used during a trial when the prosecution presented insufficient evidence. After George Ruggle's 1615 play "Ignoramus", it came into popular use to mean "fool" or "dunce."
