Which literary term refers to a recurring motif that provides thematic depth in a narrative?

The term that signifies a recurring motif which contributes thematic depth in a narrative is known as a motif. A motif is a repeated element—whether a symbol, theme, or idea—that appears throughout a literary work and helps to reinforce the overarching themes or messages. By reintroducing this element, authors can evoke emotions, create connections, or highlight key concepts, thus enhancing the reader's understanding and engagement with the narrative.

Other options, while related, serve different functions. A thematic element refers to the broader themes within a narrative without emphasizing the recurrence of specific motifs. A symbol denotes a specific object, person, or event that represents a larger idea or concept, often distinct from the broader thematic consistency that a motif provides. An archetype is a typical character, action, or situation that represents universal patterns in human nature, but it does not explicitly denote recurrence in the same way a motif does. Therefore, 'motif' is the most precise term for a recurring thematic element.
