This book investigates the use of impoliteness strategies and sub-strategies in line with Culpeper's (1996) Impoliteness Theory. It argues that pragmatic tool such as the Impoliteness theory can be applied to literary discourse to explain different dynamics in the conversation of dramatic characters. It consists of a literary work written in English by a British dramatist. This is ''Look Back in Anger'' henceforth (LBA) by John Osborne. The text is analyzed to see how gender affects characters' use of impoliteness. LBA is examined from a literary perspective in relation to its plot, structure, themes, literary language, and historical, social and political background. In addition, both qualitative and quantitative analyses of the identified strategies and sub-strategies are conducted in terms of frequency and percentages of occurrences of each strategy and sub-strategy.
