What does uncase mean?
Uncase is a relatively uncommon English verb whose basic sense is to remove something from a case, box, or protective housing. It can therefore describe taking a precision instrument out of its fitted case or opening packaging that has arrived for use. In printing and text production, uncase has the more specialized meaning of converting capitals to lowercase. The word is chiefly transitive and is more often encountered in formal, military, nautical, or technical writing than in ordinary conversation. One established ceremonial expression is "uncasing the colours." The verb's simple force is useful because it makes the reversal of an enclosure explicit rather than simply saying that something has been opened. In typography, it similarly names the deliberate removal of capital status from a character. The term is formal and specialized enough that many modern speakers will meet it in historical, military, or publishing contexts before encountering it in everyday conversation.

Where does uncase come from?
English uncase was formed by combining the prefix un- with case, giving it the sense of removing something from a case or reversing the act of enclosure. Case also supplied the related terms casing and lowercase, reflecting the established use of case for letter forms and type compartments. Encase was likewise formed on the same base, with the contrasting sense of placing something inside a covering.
