A recurring idea, image, or a group of images that unifies a work of literature is

Step 1: Analyze the question The question asks for the term describing a recurring idea, image, or group of images that helps unify a literary work.

Step 2: Explain the concepts

• Motif: A recurring element (an idea, image, symbol, or group of related images) that appears repeatedly in a work and helps develop or unify its theme. Examples: the recurring image of the locust in Chinua Achebe's Things Fall Apart, or the repeated use of blood in Macbeth.
• Allusion: A brief, indirect reference to a person, place, event, or another literary work (e.g., a biblical or historical reference). It is not a recurring unifying element.
• Legend: A traditional story handed down through generations, often partly historical but not fully verifiable (e.g., the legend of Sundiata).
• Anecdote: A short, interesting or amusing story about a real person or incident.

Step 3: Match the definition to the options The key phrase is "recurring... that unifies a work". Only a motif is defined by repetition across a work to reinforce its theme.

• Allusion refers to something outside the text and is not necessarily repeated.
• Legend is a type of story, not a device of repetition.
• Anecdote is a short narrative, not a unifying device.

Step 4: Answer The correct option is A. motif.

Exam tip: Think "motif = repeated". If a question mentions recurring or repeated in a literary-terms question, motif is almost always the answer. Don't confuse it with theme (the central message), which the motif helps to develop.
