Sonnet

Definition:
A fourteen line poem, usually in iambic pentameter, with a varied rhyme scheme. The two main types of sonnet are the Petrarchan (or Italian) and the Shakespearean. The Petrarchan Sonnet is divided into two main sections, the octave (first eight lines) and the sestet (last six lines). The octave presents a problem or situation which is then resolved or commented on in the sestet. The most common rhyme scheme is ABBA ABBA CDE CDE, though there is flexibility in the sestet, such as CDC DCD.
