A person who pretends to be someone else, often for entertainment or to deceive others.
The impersonator did a fantastic job mimicking the famous singer's voice.
Impersonator → It is formed from "im-" (meaning in or into) and "persona" (from Latin, meaning mask or character) and "-ator" (meaning one who). The word describes someone who takes on the character or role of another, effectively putting on a mask of that person.
Think of someone who puts on a 'mask' ('persona') to become another person ('im-') — that's what an impersonator does.
