fourth wall

idiom
Meaning

The imaginary invisible wall at the front of the stage in a proscenium theatre, through which the audience sees the action in the world of the play.


Origin

first recorded 18th c.

A reference to the three walls of a box set, with the fourth wall being the imaginary wall separating the performers from the audience. Coined by philosopher and art critic Denis Diderot in 1758 and thus a calque of French quatrième mur.

Examples
SIMPLE

The actor looked at the camera and broke the fourth wall.

CONTEXTUAL

The play became much funnier when the main character started talking directly to the audience, effectively breaking the fourth wall.

COMPLEX

By having the protagonist acknowledge the audience's presence, the director cleverly dismantled the fourth wall to challenge the viewer's passive role in the narrative.
