Usage

What does discovery mean? A discovery is something that has been discovered—found or found out about for the first time. Discovery can also mean the process of discovering. Discoveries involve finding or gaining knowledge about something that was previously unknown or unseen. The word is especially associated with finding new places (as in the discovery of new lands) and scientific breakthroughs (as in the discovery of a cure). The word discovery is also used in a much more specific way in the context of law, in which it refers to the required disclosure of things like documents to the other party during a legal proceeding, as in These invoices were produced by client during discovery. Example: Ancient Oceanic peoples discovered new methods of seafaring that allowed their discovery and settlement of faraway islands.

Explanation

The noun discovery means the finding or uncovering of something. The discovery of a body is usually an important plot point in a mystery novel. The process of finding, realizing, or unearthing something is discovery, like your discovery of a live lizard in the birthday box your aunt mailed from Arizona. The lizard is also a discovery — the thing that is found. In law, discovery means the obligation to reveal any relevant documents to the opposing party in a legal case. The Latin root, discooperire, basically translates as "the opposite of covering something up."
