Relative Pronouns: Who, Which and Where

A relative pronoun is a pronoun that introduces a relative clause. It's called a "relative" pronoun because it "relates" to the word that it modifies. Here is an example:

• The person who phoned me last night is my teacher. --> In the above example, "who":

- Relates to "person", wich it modifies;

- Introduces the relative clause "who phoned me last night"

There are three most important relative pronouns: who, which and where.

WHO

• It's used to refer to people: 

Example: " I know a girl who lives in your street." (Conheço uma rapariga que vive na tua rua.)

WHICH

• It's used to refer to things:

Example: " This is the phone which I bought at the weekend." (Este é o telefone que comprei no fim de semana.)

WHERE

• It's used to refer to places:

Example: " This is the house where I was born." (Esta é a casa onde eu nasci.)
