An acrostic poem is a type of poetry where the first letter of each line spells out a word or message when read vertically. This form of poetry can be used to express feelings, describe a subject, or convey a theme. For example, if the word is LOVE, each line of the poem would start with the letters L, O, V, and E, creating a meaningful connection to the word itself. Acrostic poems are often simple and fun to write, making them popular in educational settings. They encourage creativity and help with vocabulary development. Writers can choose any word or phrase as the basis for their poem, allowing for endless possibilities and personal expression.
