'O brawling love, O loving hate' 'feather of lead', 'bright smoke'
presents the agonising experience of courtly love and the confusion it causes to Romeo
oxymorons show his conflicted mind about how he is in so much pain for his 'love' for rosaline and confusion he faces on whether to seek her love
'o' sound elongates feelings and agony
courtly love often entails the knight adoring the lady with almost religious devotion
unending list of oxymorons suggests Romeo's inability to comprehend what is in front of him and his confusion on love
speech with oxymorons is 13 lines suggesting it is an imperfect sonnet alluding to the fact courtly love is not true
