Answer:
A thematic connection between two texts
Step-by-step explanation:
The term intertextuality refers to the relationship between multiple literary texts, the way a text is shaped by another text.
The phrase that best defines intertextuality is the thematic connection between two texts. For example, both texts could tell about the Second World War. There will be some differences, but there will be some similarities, as well. The older text could influence the one that was written later. In literature, this pattern is present in countless cases.
