Intertextuality is the shaping of a text's meaning by another text. It is the interconnection between similar or related works of literature that reflect and influence an audience's interpretation of the text. Intertextuality is the relation between texts that are inflicted by means of quotations and allusion. Intertextual figures include: allusion, quotation, calque, plagiarism, translation, "pastiche" and parody. It is a literary device that creates an 'interrelationship between texts' and generates related understanding in separate works. These references are made to influence the reader and add layers of depth to a text, based on the readers' prior knowledge and understanding. The structure of intertextuality in turn depends on the structure of influence. It is also a literary discourse strategy utilised by writers in novels, poetry, theatre and even in non-written texts (such as performances and digital media). Examples of intertextuality are an author's borrowing and transformation of a prior text, and a reader's referencing of one text in reading another.
