Your...life may be of no consequence to anyone else but is invaluable to you because it's the only one you've got. Exactly the same is true of each individual deer, hare, rabbit, fox, fish, pheasant and butterfly.
—Brigid Brophy
apostrophe
Words that are spoken to a person who is absent or imaginary, or to an object or abstract idea. The poem God's World by Edna St. Vincent Millay begins with an apostrophe: "O World, I cannot hold thee close enough!/Thy winds, thy wide grey skies!/Thy mists that roll and rise!"
