An actor (sometimes actress for female; see terminology) is a person who acts in a dramatic or comic production and who works in film, television, theatre, or radio in that capacity. The ancient Greek word for an "actor," ὑποκριτής (hypokrites), means literally "one who interprets"; in this sense, an actor is one who interprets a dramatic character.

After 1660, when women first appeared on stage, actor and actress were initially used interchangeably for female performers, but later, influenced by the French actrice, actress became the usual term. The etymology is a simple derivation from actor with ess added. The word actor refers to a person who acts regardless of gender, and this term "is increasingly preferred", while actress refers specifically to a female person who acts. Actress "remains in general use", although in a survey of a "wide cross-section of current British English", compiled in 2010, actor was almost twice as commonly found as actress. Within the profession, however, the re-adoption of the neutral term dates to the 1950s–60s, the post-war period when women's contribution to cultural life in general was being re-evaluated.Actress remains the common term used in major acting awards given to female recipients.
