Terza rima
Terza rima (, also US: , Italian: [ˈtɛrtsa ˈriːma]; lit. 'third rhyme') is a rhyming verse form, in which the poem, or each poem-section, consists of tercets (three-line stanzas) with an interlocking three-line rhyme scheme: The last word of the second line in one tercet provides the rhyme for the first and third lines in the tercet that follows ( A B A B C B C D C {\displaystyle \mathrm {ABA\,\,BCB\,\,CDC} } ). The poem or poem-section may have any number of lines (not divisible by 3), but it ends with either a single line or a couplet, which repeats the rhyme of the middle line of the previous tercet ( Y Z Y Z {\displaystyle \mathrm {YZY\,\,Z} } or Y Z Y Z Z {\displaystyle \mathrm {YZY\,\,ZZ} } ).
