found: Baldick, C. The Oxford dict. of literary terms, 2008(sestina. A poem of six 6-line stanzas and a 3-line envoi, linked by an intricate pattern of repeated line-endings. The most elaborate of the medieval French fixed forms, it uses only six end-words (normally unrhymed), repeating them in a different order in each stanza so that the ending of the last line in each stanza recurs as the ending of the first line in the next. The envoi uses all six words, three of them as line-endings)

A 39-line poem consisting of six stanzas of six lines each and a final three-line envoy, an addition to a poem addressed to a person or an abstraction. Adding to the complexity of the form is the requirement that each stanza use the same end words, but always in a different order.)
