persona

Persona literally means "mask ", although it does not usually refer to a literal mask but to the "social masks" all humans supposedly wear.

A persona, in the word everyday usage, is a social role or a character played by an actor. This is an Italian word that derives from the Latin for "mask" or "character", derived from the Etruscan word "phersu", with the same meaning. Popular etymology derives the word from Latin "per" meaning "through" and "sonare" meaning "to sound", meaning something in the vein of "that through which the actor speaks", i.e. a mask (early Greek actors wore masks).
