What does discover mean?
Discover means to find something or become aware of something for the first time, whether through deliberate search, scientific investigation, or sheer accident. The word carries a sense of revelation: what is discovered already exists, but was previously unknown or hidden, as when explorers discovered a continent or researchers discovered a cure. It also covers the quieter act of learning or realizing a fact, as in discovering that a friend shares your birthday. Grammatically, discover takes either a direct object (a place, an object, a truth) or a clause beginning with 'that' or a question word. Its derivatives include discovery, discoverer, and discoverable. Because it implies prior concealment or ignorance rather than creation, it contrasts with verbs like invent, which applies to bringing something entirely new into being. The word suits both elevated and ordinary registers.

Etymology of discover
Discover comes from the Old French 'descovrir', formed from the Latin prefix 'dis-' (expressing reversal) plus 'cooperire', meaning 'to cover completely' — so its literal original sense was 'to uncover' or 'remove a cover from'. English adopted it in the Middle Ages, and over time the concrete sense of physically unveiling shifted toward the figurative one of revealing knowledge or finding what was hidden. It shares this Latin root 'cooperire' with words such as cover, recover, and covert, making them distant cousins within the same etymological family.

How discover is actually used
Standard in all registers, from everyday conversation to scientific writing. In formal academic contexts, 'identify' or 'determine' may be preferred when the finding results from deliberate investigation rather than chance. The past tense 'discovered' frequently appears with a that-clause to mean simply 'found out'.
