See note below: Poetry in which every word begins with a successive letter of the alphabet. The first word begins with A, the second with B, etc. (OR) A poem that has 5 lines that create a mood, picture, or feeling. Lines 1 through 4 are made up of words, phrases or clauses - and the first word of each line is in alphabetical order from the first word. Line 5 is one sentence, beginning with any letter.
Note: ABC as a form has been used to describe anything from an Abecedarian poem (above), to an Acrostic poem, and other things. ABC typically has been used as a catch-all for sequential alphabet poems that may not necessarily use the entire alphabet like an Abecedarian poem. So, in reality, "ABC" is just an acrostic poem using successive letters of the alphabet per line or stanza.
An ABC composition is the kind of poem where every word starts with a consecutive letter of the alphabet. In this type of poem, where a first word starts with A, its second word starts with B and it goes on like that. It can also depict poems where each line starts with a consecutive letter of the alphabetical order. These lines, usually 5 in number, create imagery, mood, and feeling where phrases 1 through to 4 are made of phrases, words and/ or clauses. The fifth line can begin with any letter and is usually composed as a sentence.
A variation of this type of poetry is where a writer can use any sound of the alphabet to start a phrase and follow it up with consecutive letters as described above. Each phrase is focused on building a central topic/theme of a poem.
While some ABC poems may cover all twenty-six letters of an alphabet, some may cover only five to six.
Abc Poem Example
A better cat doesn't exist, four gentle hearts insist. Juggling kittens, leaping, mewing, now overturning pillows--quietly rush, sustain terror--understand: Vitality will explode yawning zzz's!
by LaVerna B. Johnson
Although things are not perfect
Because of trial or pain
Continue in thanksgiving
Do not begin to blame
Even when the times are hard
Fierce winds are bound to blow
