What is acrostic?

An acrostic is a poem or other form of writing in which the first letter of each line or paragraph spells out a word or message. It can be used as a form of word puzzle, where the reader is challenged to decipher the hidden message. Acrostics have been used throughout history in religious texts, literature, and even as a way to remember important information. They are often used in children's books and educational settings as a fun and creative way to enhance learning. Modern variations include online acrostics, where the words can be interactive and animated.
