Here's why:
* Pronouns stand in for nouns. They replace nouns to avoid repetition.
* Nouns are words that name people, places, things, or ideas.
Examples:
* Which book did you choose? (Here, "which" replaces a specific book.)
* The red book is mine. ("Book" is the noun)
Types of Pronouns:
"Which" is a relative pronoun. Relative pronouns connect clauses in a sentence and refer back to a noun or pronoun mentioned earlier.
Other common relative pronouns include:
* who
* whom
* whose
* that
