What is an allusion in literature?

An allusion in literature refers to a cultural or historical reference that the author expects the reader to recognize and understand. This can include references to well-known events, figures, works of literature, myths, or cultural practices. By employing allusions, writers can create deeper meanings or connections within their work, drawing on the shared knowledge and experiences of their audience. This technique can enrich the text and evoke emotions or reactions based on the referenced material, allowing for a more nuanced understanding of the themes or ideas being presented. Through this indirect reference, an author can layer additional significance onto their writing without having to elaborate extensively, relying on the reader's prior knowledge to fill in those gaps.
