Sapphic stanza
The Sapphic stanza, named after Sappho, is an Aeolic verse form spanning four lines (more properly three, in the poetry of Sappho and Alcaeus, where there is no word-end before the final Adonean).
The form is two hendecasyllabic verses, and a third verse beginning the same way and continuing with five additional syllables (given as the stanza's fourth verse in ancient and modern editions, and known as the Adonic or adonean line).
