The word "caption" refers to a brief explanation or description accompanying an illustration, photograph, or other image. It often provides context or additional information to help the viewer understand what the image represents. Captions are commonly found in books, articles, and online media.
The word "caption" comes from the Latin word "captio," which means "taking" or "seizing." Its usage evolved through Old French before entering the English language in the late Middle Ages, referring to the act of taking a hold of or capturing something in words.
