What are captions in non-fiction texts?

In non-fiction texts, captions are short descriptions or explanations accompanying an image or illustration. Captions serve to provide additional information, context, or insight related to the visual content. They are commonly found in textbooks, newspapers, magazines, and other informational materials. Captions play a crucial role in elucidating the significance of the visual elements and enhancing the reader's understanding of the subject matter. By incorporating captions, non-fiction texts strive to complement the written content with visual aids, thereby enriching the overall reading experience for students.
