structure. The English sonnet, also known as the Shakespearean sonnet, consists of three quatrains (four-line stanzas) followed by a concluding couplet (two-line stanza). The rhyme scheme of an English sonnet is typically ABAB CDCD EFEF GG.
On the other hand, the Italian sonnet, also known as the Petrarchan sonnet, is divided into an octave (eight-line stanza) and a sestet (six-line stanza). The octave usually follows the ABBA ABBA rhyme scheme, while the sestet can have various rhyme schemes such as CDE CDE or CDC DCD.
To identify the differences in structure between the English and Italian sonnet, you can analyze the number and arrangement of stanzas as well as the rhyme scheme used in each.
