Step-by-step explanation:
allusion, in literature, an implied or indirect reference to a person, event, or thing or to a part of another text. Most allusions are based on the assumption that there is a body of knowledge that is shared by the author and the reader and that therefore the reader will understand the author's referent.
Some common allusion examples include: To my dog, our neighborhood park is the Garden of Eden. (alludes to the Christian Bible)
