What does wig mean?
A wig is a false head of hair worn on the scalp, either as a disguise or as part of a costume, theatrical performance, or distinctive personal style. The word is standard in both British and American English, although it can sound old-fashioned or deliberately theatrical when describing a formal, powdered, or elaborate hairpiece. In informal usage, 'wig' can also function as a verb meaning to pretend or deceive, often playfully: someone might wiggle their way into gaining access or attention. The separate expression 'wig out' means to become extremely excited or animated. These meanings make wig unusually versatile: it can refer to an object associated with appearance and disguise, but also to theatrical behavior. The noun is countable and commonly pluralized as 'wigs,' while the verb belongs mainly to informal registers rather than formal writing.
