The ABABCDCDEFEFGG rhyme scheme is characteristic of the Shakespearean sonnet, a poetic form popularized by William Shakespeare. This structure consists of 14 lines divided into three quatrains followed by a final rhymed couplet. Each quatrain introduces a new idea or theme, while the couplet often provides a resolution or commentary. In this format, the first and third lines of each quatrain rhyme with each other, as do the second and fourth lines, creating a pattern of alternating rhymes. The final couplet, consisting of two lines, typically rhymes with each other, providing a conclusive thought or twist to the poem's overall message.
