Explain the concept of possessive determiners and provide examples.

Possessive determiners are a type of pronoun that indicate ownership or possession. They are used to show that something belongs to someone or something else. Possessive determiners are also known as possessive adjectives.

Examples of possessive determiners include:

1. My: This shows that something belongs to the speaker. For example, "This is my book."

2. Your: This shows that something belongs to the person being spoken to. For example, "Is this your car?"

3. His: This shows that something belongs to a male person or animal. For example, "That is his house."

4. Her: This shows that something belongs to a female person or animal. For example, "She lost her keys."

5. Its: This shows that something belongs to a non-living thing or an animal. For example, "The dog wagged its tail."

6. Our: This shows that something belongs to a group of people including the speaker. For example, "We are going to our friend's party."

7. Their: This shows that something belongs to a group of people not including the speaker. For example, "They lost their wallets."

These possessive determiners are used before a noun to indicate ownership or possession. They agree in number and gender with the noun they modify. It is important to note that possessive determiners are different from possessive pronouns, which are used to replace a noun and show ownership without being followed by a noun.
