alphabetical acrostic: A poem where the first letter of each line, when read vertically, follows the sequence of the alphabet from A to Z. This structured form requires twenty-six lines and challenges poets to maintain coherence while adhering to alphabetical constraints. Beyond simple letter ordering, effective alphabetical acrostics integrate the constraint meaningfully with content, creating works that read naturally despite their systematic structure. The form serves educational purposes, mnemonic functions, and demonstrates technical virtuosity while exploring how arbitrary constraints can generate creative possibilities.

Alphabetical acrostic uses the alphabet sequentially to begin each line or stanza. Unlike random acrostics, this form follows A-B-C order, creating structure through the alphabet while developing theme or narrative. Common in medieval and religious poetry.
