A thespian is an actor or actress. The term comes from Thespis, a Greek playwright and performer who is credited with adding a new dimension to drama by stepping out of the Greek chorus during a performance and reciting portions of the text alone, becoming the first actor. Thespian with an uppercase "T" refers to a member of the International Thespian Society, the worlds largest honor society for theatre students. Junior Thespians are middle school/junior high members of ITS.
