An Abecedarian hymn is a devotional or liturgical poem structured according to the sequence of the alphabet, where each stanza, line, or section begins with successive letters from A to Z (or the equivalent in the relevant language’s script); this form originated in ancient Hebrew poetry (e.g., Psalm 119) and was later adopted in Christian liturgical traditions to aid memorization and symbolize completeness or divine order—its alphabetical scaffolding often serves both mnemonic and theological purposes, reinforcing the idea of encompassing all aspects of praise or lament within a divinely ordained structure.

Religious didactic verse ordered alphabetically, popular in early Christian and medieval periods. Psalm 119 is the famous Biblical example. Aids memorization while teaching doctrine.
