Relative Clauses Questions Medium
Relative clauses used in non-defining contexts provide additional information about a noun or pronoun in a sentence, but they are not essential to the meaning of the sentence. They are usually set off by commas. Here are some examples:
1. My sister, who is a doctor, lives in New York.
2. The Eiffel Tower, which was built in 1889, is a famous landmark in Paris.
3. John's car, which is parked outside, needs a new battery.
4. The book, which I borrowed from the library, was very interesting.
5. The dog, whose tail wags constantly, loves to play fetch.
In these examples, the relative clauses provide additional information about the noun or pronoun they modify, but if they were removed, the main sentence would still make sense.
