What are the rules for using possessive adjectives?

The rules for using possessive adjectives are as follows:

1. Possessive adjectives are used to show ownership or possession of something. They indicate who something belongs to.

2. Possessive adjectives agree in gender and number with the noun they modify. In English, the possessive adjectives are: my, your, his, her, its, our, and their.

3. Possessive adjectives are always placed before the noun they modify. For example, "my book," "his car," "our house."

4. Possessive adjectives are not used with articles. For example, we say "my book" instead of "the my book."

5. Possessive adjectives can also be used to show relationships or connections between people. For example, "my sister," "his friend," "our teacher."

6. Possessive adjectives do not change form when used with plural nouns. For example, "my books," "your friends," "their houses."

7. Possessive adjectives are used to indicate possession, but they do not show ownership in a legal sense. For legal ownership, we use the possessive form with an apostrophe ('s) or just an apostrophe (').

It is important to note that possessive adjectives are different from possessive pronouns. Possessive adjectives modify nouns, while possessive pronouns replace nouns.
