What is the significance of Juliet’s speech? What is she saying about names, language, and identity? What is her solution to the obstacle the Capulet and Montague names present?

JULIET O Romeo, Romeo! wherefore art thou Romeo? 35
Deny thy father and refuse thy name;
Or, if thou wilt not, be but sworn my love,
And I'll no longer be a Capulet.
ROMEO [Aside] Shall I hear more, or shall I speak at this?
JULIET 'Tis but thy name that is my enemy; 40
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 45
By any other name 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 that name which is no part of thee 50
Take all myself.
