An Implicatural Study of Iago's Speeches in Othello This study presents an analysis of Iago's speeches in the play Othello by Shakespeare. For this purpose the researcher has applied Paul Grice's Theory of Implicature. The study focuses on Iago's speeches as an example of flouting of the maxims of the Cooperative Principle. A total of fifty-two speeches have been selected and analysed in the light of Grice's theory. The speeches have been studied carefully and categorized according to the four maxims (Quantity, Quality, Relation, and Manner) of the Cooperative Principle. Brief analyses accompany individual speeches. The hypothesis that Iago willfully flouts Grice's maxims in order to achieve his nefarious purposes is proved with the help of this analysis. The study leads to the conclusion that a study of other literary texts, on the same pattern, may enhance comprehension and appreciation of literary texts in general. The application of Grice's theory to Shakespeare's play will add new dimension to Shakespearean criticism and be of great interest for students and teachers of literature.
