Read the passage. excerpt from Act V, Scene 1, in A Midsummer Night's Dream by William Shakespeare
Shakespeare's version of Ovid's Pyramus and Thisbe myth

Pyramus
O grim-look’d night! O night with hue so black!
O night, which ever art when day is not!
O night, O night! alack, alack, alack,
I fear my Thisby’s promise is forgot!
And thou, O wall, O sweet, O lovely wall,
That stand’st between her father’s ground and mine!
Thou wall, O wall, O sweet and lovely wall,
Show me thy chink, to blink through with mine eyne!
Refer to Explorations in Literature for a complete version of this scene from the play.
Pyramus uses the word O 10 times in this speech to address the wall or the night.
How does this repeated word affect the speech?

It makes Pyramus seem both passionate and ridiculous.

It makes the wall and the night seem like active characters.

It makes a basically unrealistic speech seem a bit more real.

It turns the speech into a powerful expression of romantic love.
