Relative pronouns

1. The relative pronouns are: who, whoever, whom, whomever, that, which, when, where, whose.
2. We use relative pronouns to join two relative clauses. Relative clauses give more information about something:
1. I bought a new car. It is very fast. → I bought a new car that is very fast.
2. She lives in New York. She likes living in New York. → She lives in New York, which she likes.
3. We also use relative clauses to give more information about a person, thing or situation. In this case, we use commas (,) to separate the relative clause from the rest of the sentence:
1. Lord Thompson, who is 76, has just retired.
2. We had fish and chips, which I always enjoy.
3. I met Rebecca in town yesterday, which was a nice surprise.
4. We use 'whose' as the possessive form of 'who':
1. This is George, whose brother went to school with me.
5. We sometimes use 'whom' as the object of a verb or preposition:
1. This is George, whom you met at our house last year. ('whom' is the object of 'met')
2. This is George’s brother, with whom I went to school. ('whom' is the object of 'with')
6. We can use 'when' with times and 'where' with places to make it clear which time or place we are talking about:
1. I remember my 20th birthday. It was the year when I met my wife.
2. Liverpool is the town where John Lennon was born.
