Literally, "the point in a literary work at which the chief dramatic complication is worked out".( Merriam Webster Online ) In literature, this usually means the point at which the primary conflict in the piece comes to a close and is solved or ended. ex. The death of both Romeo and Juliet, though an anti-climax, served as the resolution for the primary conflict of the story.
