What is a picture book primarily characterized by?

A picture book is primarily characterized by the use of many illustrations, which play a crucial role in conveying the story or message. These books are designed to engage young readers through vivid images that complement or enhance the text. Illustrations provide visual context, helping to spark imagination and understanding, especially for early readers who may not yet have strong reading skills.

In contrast, while detailed text descriptions, historical accounts, or poetic verses may appear in certain types of literature, they are not defining features of picture books. Picture books often rely on a balance of visual and textual elements; however, the illustrations are the standout characteristic that makes them unique and appealing to their target audience.
