1. What's a Relative Pronoun? Relative pronouns are used to combine sentences and to avoid redundancy in writing. They are used to introduce relative clauses--parts of sentences that describe, define or expand on something already referred to in the sentence--and in English, the relative pronouns are usually who, whom, which, or that: I need the book which is in your bag. Julie is a person whom I hold in the highest esteem. What is the title of the paper to which you referred earlier?   In each of these sentences, the relative pronoun is in bold, and the relative clause is in blue (the rest of the sentence could stand alone without it.) In English, we often omit the relative pronoun (Julie is a person I hold in the highest esteem.) but in French, you must always use it.

To choose the correct relative pronoun in French, you need to ask two questions: 1. What is the grammatical function of the pronoun in the relative clause? 2. Are we referring to a person or a thing? Let's ask these questions of our example sentences. I need the book which is in your bag. Look at the relative clause (la subordonnée) --which is in your bag – 1. is which the subject of the verb is, or its object, or is it the object of a preposition? 2. Does which refer to a person or a thing?

Example: Julie is a person whom I hold in the highest esteem. Look at the relative clause --whom I hold in the highest esteem – 1. Is whom the subject of the verb hold, or its object, or is it the object of a preposition? 2. Does whom refer to a person or a thing? Try this one: What is the title of the paper to which you referred earlier? Look at the relative clause --to which you referred earlier – 1. Is which the subject of the verb referred, or its object, or is it the object of a preposition? 2. Does which refer to a person or a thing?
