sonnet

A sonnet is a fixed poetic form with a structure traditionally consisting of fourteen lines adhering to a set rhyming scheme. The term derives from the Italian word sonetto. Originating in 13th-century Sicily, the sonnet was in time taken up in many European-language areas, mainly to express romantic love at first, although eventually any subject was considered acceptable. Many formal variations were also introduced, including abandonment of the quatorzain limit – and even of rhyme altogether in modern times. Read more on Wikipedia
