Explain the usage of the relative pronouns as determiners.

Relative pronouns can also function as determiners in a sentence. Determiners are words that come before a noun and provide information about the noun. When relative pronouns are used as determiners, they introduce a relative clause that provides additional information about the noun.

The relative pronouns that can be used as determiners are "whose," "which," and "that."

1. "Whose" is used to show possession or ownership. It is used to introduce a relative clause that provides information about the noun it modifies. For example, "The man whose car was stolen reported it to the police." Here, "whose" is a determiner that introduces the relative clause "whose car was stolen" and provides information about the noun "man."

2. "Which" is used to provide additional information about a noun. It is used to introduce a relative clause that gives more details about the noun it modifies. For example, "The book, which is on the shelf, is my favorite." Here, "which" is a determiner that introduces the relative clause "which is on the shelf" and provides additional information about the noun "book."

3. "That" is used to introduce a restrictive relative clause, which means it provides essential information about the noun it modifies. It is commonly used with both people and things. For example, "The dog that barks loudly is annoying." Here, "that" is a determiner that introduces the relative clause "that barks loudly" and provides essential information about the noun "dog."

In summary, relative pronouns can function as determiners when they introduce relative clauses that provide additional information or essential details about the noun they modify.
