Relative pronouns are primarily used for what purpose?

Relative pronouns serve the primary function of connecting clauses or phrases to nouns. They introduce relative clauses, which provide additional information about a noun. For instance, in the sentence "The book that I borrowed was fascinating," the relative pronoun "that" links the clause "that I borrowed" to the noun "book," offering more context about which specific book is being discussed.

This ability to introduce additional information makes relative pronouns essential for creating complex sentences that enhance clarity and detail. In contrast, the other choices represent different grammatical functions. Asking questions is typically performed with interrogative pronouns, while emphasizing nouns often involves demonstrative or emphatic structures. Indicating possession is the role of possessive pronouns, not relative ones. Therefore, the connection of clauses or phrases to nouns is the defining purpose of relative pronouns.
