Accentual verse

Verse whose meter is determined by the number of stressed (accented) syllables—regardless of the total number of syllables—in each line. Many Old English poems, including Beowulf, are accentual; see Ezra Pound’s modern translation of “The Seafarer.” More recently, Richard Wilbur employed this same Anglo-Saxon meter in his poem “Junk.” Traditional nursery rhymes, such as “Pat-a-cake, pat-a-cake,” are often accentual.

Accentual-syllabic verse

Verse whose meter is determined by the number and alternation of its stressed and unstressed syllables, organized into feet. From line to line, the number of stresses (accents) may vary, but the total number of syllables within each line is fixed. The majority of English poems from the Renaissance to the 19th century are written according to this metrical system.

Acmeism

An early 20th-century Russian school of poetry that rejected the vagueness and emotionality of Symbolism in favor of Imagist clarity and texture. Its proponents included Osip Mandelstam and Anna Akhmatova.

Acrostic

A poem in which the first letter of each line spells out a word, name, or phrase when read vertically. See Lewis Carroll’s “A Boat beneath a Sunny Sky.”

Alcaic

A four-line stanza invented by the Classical Greek poet Alcaeus that employs a specific syllabic count per line and a predominantly dactylic meter. Alfred, Lord Tennyson imitated its form in his poem “Milton.”
