What is a Rhyming Couplet?
The Rhyming Couplet is the last two lines of the sonnet that have the same rhyme scheme.
For example...
But day doth daily draw my sorrows longer, A
And night doth nightly
make grief's length seem stronger A
Shakespeare purposefully made the rhyming couplet because he wanted to express the full meaning of the sonnet in the last two lines. As mentioned before, Shakespreare wrote for us, not for the the significantly more elite upper class. He did not write with a bunch of riddles, he told us what the meaning was straight up. The reason the rhyming couplet is rhymed that way is because it is apparent and stands out to the audience, thus allowing them to capture the meaning of the poem.
