What are the rules for using determiners with possessive nouns?

The rules for using determiners with possessive nouns are as follows:

1. Possessive determiners: Possessive determiners are used to show ownership or possession. They include words like my, your, his, her, its, our, and their. These determiners are used before a noun to indicate that the noun belongs to someone or something. For example, "This is my car" or "Their house is beautiful."

2. Possessive pronouns: Possessive pronouns are used to replace a noun and show ownership. They include words like mine, yours, his, hers, its, ours, and theirs. These pronouns are used without a noun following them. For example, "The book is mine" or "The house is theirs."

3. Placement of determiners: When using possessive determiners or pronouns, they are placed before the noun they modify. For example, "His dog is friendly" or "Our car is parked outside."

4. Agreement with the noun: Possessive determiners and pronouns should agree in number and gender with the noun they modify. For example, "Her cats are playful" or "Their children are talented."

5. Avoiding double possessives: It is important to note that possessive determiners and pronouns already indicate possession, so it is not necessary to use an additional possessive noun. For example, instead of saying "John's car's color is red," it is more appropriate to say "John's car is red."

Overall, the rules for using determiners with possessive nouns involve using the appropriate possessive determiner or pronoun, placing it before the noun, ensuring agreement with the noun in number and gender, and avoiding double possessives.
