What does uncap mean?
Uncap is a transitive verb meaning to remove a cap or covering from something. Its literal uses include taking off a bottle's cap, a vial's cap, or a protective cover. The word also has an established figurative use meaning to remove an upper limit or restriction, especially from prices, fees, or production. In that sense, uncap describes lifting a ceiling that would otherwise constrain what can be charged or produced. The verb is less common than cap and often sounds more technical or institutional than conversational. It is usually used transitively, although the direct object may be omitted when the subject is understood. The word is useful because it compresses two related ideas: uncovering something and removing an artificial ceiling. Its short form makes it especially at home in financial, industrial, and technical discussion.

Where does uncap come from?
Uncap was formed in English by combining the prefix un- with cap, producing the reverse of capping something or setting a limit on it. Cap comes through Old English cappa and Late Latin cappa from Latin caput, meaning "head." The same Latin root underlies related words such as captive, capture, and capital.
