What are examples of:symbolism, an aside, foreshadowing, and figurative language, in Romeo and Juliet?
Regarding figurative language, the entire play is a poem as it is written in blank verse except for the three sonnets: the one in which Romeo meets Juliet--"If I profane with my unworthiest hand"--in Act I, Scene 5; and the sonnets of the Prologue to the play and the Prologue to Act II.
Then, of course, the play is replete with light/dark imagery. For example, when Romeo first sees Juliet in Act I, Scene 5, he remarks,
O, she doth teach the torches to burn bright!
It seems she hangs upon the cheek of night
As a rich jewel in an Ethiop's ear;
Beauty too rich for use, for earth too dear!
So shows a snowy dove trooping with crows,
As yonder lady o'er her fellows shows....
When Juliet gives her speech about what's in a name, a rose still smells as sweet, etc. The rose is the symbol of Romeo's name, the flower, and the love that is blooming between them. It could also be symbolic of the strife between their families which is why his name is so important, and deadly to her family.
For foreshadowing, Act III, Scene 5, line 55 when Juliet tells Romeo he looks pale, like a dead person in the bottom of a tomb.
For an aside, Act II, Scene 2 -- the balcony scene. Romeo is listening to Juliet but she doesn't know he's there. (Line 39 is Romeo's aside).
Oxemorons are available when we see words like : " love hates " or Living dead " light dark ". For oxemorons are present when we use opposite words in the same sentence.
We can also see the pun when Mercutio says : Tomb man or graveyard man for it resmbeles two meanings.
there is comic relief or Satire when Mercutio and Tybalt for he started making fun about him.
There is an aside when we see in Act I Romeo talking with the maid.
There is also an irony after they slept together, he woke up and wanted to go in a hurry but she said to him to stau after a moment we see the opposite " she is telling him to go but he doesn`t want to. :
Another irony , dramatic irony , is when we know that juliet is not dead but Romeo thinks she is dead and kills himself .
You could use any one of the longer soliloquies in the play to find your specific references. The balcony scene is the most popular; it is rich in figurative language. Or, the death scenes.
