Explain the powerful image in this quotation from romeo and juliet
’tis but thy name that is my enemy; thou art thyself, though not a montague. what’s montague? it is nor hand nor foot, nor arm nor face, nor any other part belonging to a man. o be some other name! what’s in a name? that which we call a rose by any other word would smell as sweet; so romeo would, were he not romeo call’d, retain that dear perfection which he owes without that title. romeo, doff thy name, and for thy name, which is no part of thee, take all myself.
