A sonnet is a type of poem that always includes fourteen verses or lines and commonly each verse has a certain structure and lines include a rhyme scheme or a pattern of sound repetition that vary according to the language and historical period. Indeed it is believed this type of poems first emerged in Italy during the 13th century and then was adopted by authors of different countries and in different centuries including famous writers such as William Shakespeare and Percy Bysshe Shelley. Therefore, according to the previous ideas, it is false a sonnet is a ten-lines poem without a rhyme scheme because a sonnet is a fourteen-line poem and in most cases follows a rhyme scheme.
