Abecedarian

Abecedarian: Noun. A form of poetry guided by the alphabet. A line or stanza begins with a letter from the alphabet and the pattern proceeds through the entire alphabet sequentially (alpha to omega, "a" to "z").

Acrostic: Noun. A technique derived from the abecedarian that spells out words or names through the first letter of each line, which serves to "hide" the message.
