Awnser: When Romeo and Juliet meet they speak just fourteen lines before their first kiss. These fourteen lines make up a shared sonnet, with a rhyme scheme of ababcdcdefefgg. A sonnet is a perfect, idealized poetic form often used to write about love. Encapsulating the moment of origin of Romeo and Juliet’s love within a sonnet therefore creates a perfect match between literary content and formal style. The use of the sonnet, however, also serves a second, darker purpose. The play’s Prologue also is a single sonnet of the same rhyme scheme as Romeo and Juliet’s shared sonnet. If you remember, the Prologue sonnet introduces the play, and, through its description of Romeo and Juliet’s eventual death, also helps to create the sense of fate that permeates Romeo and Juliet. The shared sonnet between Romeo and Juliet therefore creates a formal link between their love and their destiny. With a single sonnet, Shakespeare finds a means of expressing perfect love and linking it to a tragic fate.
