What is a caption?

A caption is a brief description or explanation that accompanies a picture, photograph, or illustration. It is used to provide additional information or context to the visual content and often includes details about the subject, location, or events depicted in the image. Captions can be found on social media posts, news articles, marketing materials, and books and are a powerful tool to engage the audience and convey a message. They are usually written in a concise and clear language and can include hashtags, links, or calls to action.
