What is an allusion in literature?

An allusion in literature is defined as a reference to a well-known person, place, event, or literary work. This technique allows writers to create deeper connections with their readers by invoking shared knowledge or experiences. Through allusion, authors can enrich their narratives, add layers of meaning, and prompt readers to draw parallels with historical, cultural, or literary contexts. For instance, a character referencing a famous historical figure can evoke certain characteristics or themes associated with that figure, thereby enhancing the character’s or the story's depth without requiring extensive explanation.

Other options may describe different literary techniques but do not convey the specific meaning of allusion. For example, a dialogue focused on character relationships pertains to character development rather than referencing external concepts. Similarly, foreshadowing is about hinting at future events in the story, while detailed description of setting relates to imagery rather than invoking external references. Thus, the answer effectively captures the essence of what an allusion is within literary studies.
