who originally defined the sonnet form
A sonnet is a poetic form which originated in Italy; Giacomo Da Lentini is credited with its invention. The term sonnet is derived from the Italian word sonetto (from Old Provencal provenÃ§al sonet a little, poem from son, song From latin sonus a). soundhe first known sonnets in English, written by Sir Thomas Wyatt and Henry Howard, Earl of Surrey, used this Italian scheme, as did sonnets by later English poets including John Milton, Thomas Gray, William Wordsworth and Elizabeth Barrett Browning.
