Rhetorical device where the speaker addresses an absent person abstraction or inanimate object?

The rhetorical device where the speaker addresses an absent person, abstraction, or inanimate object is called apostrophe.

Here are some examples:

* Addressing an absent person: "Oh, Romeo, Romeo! Wherefore art thou Romeo?" (from Shakespeare's *Romeo and Juliet*)

* Addressing an abstraction: "O Death, where is thy sting?" (from the Bible, 1 Corinthians 15:55)

* Addressing an inanimate object: "O, you cruel, cruel ocean! You took my love from me!" (from a poem)

Apostrophe is often used to create a sense of emotional intensity or to emphasize a particular point. It can also help to make the speaker's thoughts and feelings more vivid and relatable to the audience.
