An alphabetic acrostic sonnet is a fourteen-line poem in which the first letter of each line sequentially follows the order of the alphabet (A through N for the octave, O through N or adjusted for the sestet), combining the structural discipline of the sonnet form with the ancient acrostic device; this hybrid form challenges the poet to maintain thematic coherence and metrical integrity while adhering to a rigid alphabetic scaffold, often resulting in inventive wordplay and constrained lyricism that foregrounds the materiality of language itself.

Acrostic sonnet where initial letters progress alphabetically through fourteen lines. Combines rigid form with alphabetic constraint. Challenging due to limited letters (14 vs 26). Related to abecedarius and acrostic.
