What are some conceit, oxymoron and sililoquies in Romeo and Juliet Shakespeare? Thanks

I'll
start with .  By definition a soliloquy is a speech that a character says to himself or herself.
 It doesn't have to be long, but it always expresses the inner thoughts, emotions, and/or
motivations of a character.  Probably the most famous soliloquy fromappears in Act 2 Scene 2
whenis standing beneath 's balcony waiting for her to appear. That's the one that starts like
this: 

"But, soft! what light through yonder window
breaks?
It is the east, and Juliet is the sun."

Anis awhere two contradictory terms...
