This document provides an overview and analysis of Eugene O'Neill's play Mourning Becomes Electra and his style and use of language. It notes that O'Neill was an influential American playwright who won the Nobel Prize in Literature. The play Mourning Becomes Electra is a modern adaptation of the Oresteia set in the modern Mannon family and explores themes of obsessive love through complex characters driven by passion. While O'Neill's style was realistic, it also had surreal elements, and he effectively used dialects for special effect though his language was not as elevated as the Greeks.
