As a dramatist Harold Pinter occupies a unique place. His plays are ordinary, simple, yet fascinating and enigmatic. The Birthday Party is a very popular play of Pinter. Pinter provides very little information about the background and motives of his characters here. We can not be sure about anything in the play. One important aspect of the play is the lack of communication, the characters resorting to silence and pause. Apparently, these silences and pauses are break in the communication. But Pinter has a definite strategy in using these. They can communicate what cannot be communicated through words. This paper attempts to review the use of silence, pause and nonsensical language in The Birthday Party and Pinter’s objectives and strategy behind the abundance of silences and pauses in the play.
