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 a literary device that creates an ‘interrelationship between texts’ and generates related understanding in separate works.[4] These references are made to influence the reader and add layers of depth to a text.
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.
So, Intertextuality is not copying and pasting,its to direct out attention, visualization texts indeed statmets and others.
Since story telling is also a social practice the western film both reflects and perpetuates the historicitis mythology of the US frontier.
