“Which” is a pronoun used to inquire about a specific choice or option among several possibilities. It is often used to introduce a relative clause and is commonly used in English language to seek information or make a selection from alternatives.
“Which” can be used as an interrogative pronoun or a relative pronoun. As an interrogative pronoun, it starts a question. For example, “Which book do you prefer?” As a relative pronoun, it introduces a relative clause that provides additional information about a noun. For example, “The car which is parked outside is mine.”
– “Which restaurant shall we go to for dinner?”
– “The dress, which was expensive, still looks brand new.”
– “Which team won the championship?”
