For example, My book is on the table. Used to modify a noun. Mine is on the table. Used as a subject. I put mine in the refrigerator. Used as an object. The red one is mine. Used as a compliment. See the table below. Pronouns as adjectives. Pronouns as subjects, objects, and compliments. My. Mine. Is. Is. Her. Hers. It's. It's. Your. Yours. Our. Ours. There. There's. The possessive is formed by adding apostrophe s to singular nouns and plural nouns not ending in s. Such possessives can be used as modifiers or they can stand alone. It is John's bicycle.
