What is the meaning of "allusion"?

The term "allusion" refers to a passing reference or indirect mention of something, typically used to enhance the meaning of a text without explicitly stating it. This literary device relies on the audience's familiarity with the referenced subject, which is often a well-known person, event, or piece of literature, allowing for deeper understanding and resonance within a piece of writing.

Choosing a definition that captures the essence of "allusion" involves recognizing that it does not require a direct or detailed explanation, which distinguishes it from choices that imply explicitness or extensive description. Instead, an allusion relies on subtlety and brevity, inviting the audience to connect the dots based on their prior knowledge.
