Etymology
Origin of discover
First recorded in 1300–50; Middle English discouere(n), descuvere(n), from Anglo-French discoverir, descovrir, from Old French descovrir, descuvrir, from Late Latin discooperīre “to disclose, expose”; see origin at dis- 1, cover
Explanation
If you discover something, you find it unexpectedly, like when you discover your favorite childhood stuffed animal in a box of old junk. When you discover something, it can be by surprise or the result of a search. You might discover the fact that your dad used to travel with the circus as a trapeze artist or discover a band none of your friends ever heard of. Scientists often discover new substances, stars, or organisms. The Latin root discooperire, "uncover," combines the prefix dis-, or "opposite of," with cooperire, "to cover up."
