Romeo is being very moody, he is expressing his feelings to Benvolio in rhyming couplets. Rhyming couplets tell the audience of Romeo's strong feeling of wanting to be left alone.
"She is the hopeful lady of my earth./But woo her gentle Paris, get her heart;/My will to her consent is but a part" (Act I, i, 15-17). Capulet is saying that Juliet is his last hope. He is speaking to Paris about getting Juliet's heart, and that his consent to the two being joined in marriage is only part of the deal. Even a secondary character like Capulet uses rhyming couplets to explain a the serious matters of marriage. The weight of even a secondary character using rhyming couplets is paramount because if a secondary character uses a device like rhyming couplets to express their feelings it shows the importance of using it to express emotion.
In the following quote, Juliet is expressing her confusion, her love and hate for her love, Romeo. At the same time, she is saying he is beautiful and ugly, a saint and a villain, he has beauty, but yet in his beauty is deceit, his good nature is hellish, he is pure and stained, he is dirty and clean, he is a killer and a lover. She is expressing her love for Romeo and her hate for his actions with oxymorons. Using oxymorons represents very strong emotions, in this case confusion. Shakespeare is using oxymorons, yet again. Oxymorons are littered throughout the play which is an effective way to reveal a characters feelings.
Beautiful tyrant! Fiend angelical.
Dove-feathered raven! Wolvish-ravening lamb!.
Despised substance of divinest show.
Just opposite to what thou justly seem'st.
A damn`ed saint, an honorable villain!.
O nature, what hadst thou to do in hell.
When thou didst bower the spirit of a fiend.
In mortal paradise of such sweet flesh?.
(Act II, ii, 75-81).
Friar Lawrence's introduction into the play begins with rhyming couplets, showing his importance in the play.
