The language and plot of The Caretaker blends Realism with the Theatre of the Absurd. In the Theatre of the Absurd language is used in a manner that heightens the audience's awareness of the language itself, often through repetition and circumventing dialogue.
The play has often been compared to Waiting for Godot, by Samuel Beckett, and other absurdist plays because of its apparent lack of plot and action.
The fluidity of the characters is explained by Ronald Knowles as follows: "Language, character, and being are here aspects of each other made manifest in speech and silence. Character is no longer the clearly perceived entity underlying clarity of articulation the objectification of a social and moral entelechy but something amorphous and contingent (41).
