The play barely reveals anything about the identity of its characters. The setting is vague, there are no props. What they speak is meaningless and repetitive.

However, the audience still knows that they are all men. Their names are Vladimir, Estragon, Lucky and Pozzo, which hints about the countries that these names are common to (Russia, Italy etc.) Pozzo and Lucky share a master and slave relationship which gets inverted later. Estragon and Vladimir are friends (equals).

The whole play starts and ends in a single setting without any changes in the scene. Waiting for Godot is a play where nothing happens. And, that itself is absurdity.
