Abstract
Literary works lead to various interpretations as the language carrying the meaning is characteristically unstableand uncertain. The present study aims to explicate the instability and uncertainty of language in the play Junoand the Paycock written by Sean O'Casey. The study is qualitative in nature as the analysis involves the subjectiveinterpretations of the text. The analysis of the purposively selected text has been carried out by applying Derrida'sconcept of deconstruction. The findings of the study reveal that the text of the play contains paradoxes andcontradictions. Furthermore, the results depict that Casey utilizes the techniques of shifts and breaks of time andtone in developing the plot of the play. In addition to that, the absences and omissions are also found in the textof the play. The findings of the study also suggest that the there are instances of linguistic quirks and aporia inthe text that question the credulity of the language itself. The significance of the study lies in the fact that it ishelpful in drawing various interpretations of the text of the play Juno and the Paycock. Therefore, it is helpful forthe readers, students of literature, and the teacher s of the literature. Furthermore, the study is helpful for theresearchers who are interested in applying the concept of deconstruction, an aspect of post- structuralism, toanalyse the literary writings.
