The act of pretending to be someone else, often to deceive others or for entertainment purposes.
The comedian's impersonation of the famous actor had the audience laughing all night.
Impersonation → It is formed from "im-" (meaning in or into) and "persona" (from Latin, meaning mask or character). The word refers to the act of taking on the character or identity of another person.
Think of 'taking on' ('im-') the 'character' ('persona') of someone else — that's what impersonation means.
