SONNET
A sonnet is a fourteen-line poem in the form of a poem. It began in Italy in the thirteenth century, and though some of the original standards have been preserved, such as the number of lines and the use of a certain rhyme scheme and meter, the norms of sonnets have altered to some extent throughout the ages.
The Italian or Petrarchan sonnet and the English or Shakespearean sonnet are the two main branches of the sonnet form.
