A relative clause gives more information about a noun in the main sentence. It is introduced by a relative pronoun. 🔹 Relative pronouns : • WHO — refers to people - The man who lives next door is a doctor. - Students who study hard get good grades. • WHICH — refers to things and animals - The book which I read was very interesting. - This is the car which my father bought. • THAT — refers to people OR things (used in defining clauses) - The girl that won the prize is my sister. - The house that they built is beautiful. • WHOSE — shows possession (de qui, dont) - The student whose work is the best will get a prize. - I met a girl whose father is a teacher. 🔹 Two types of relative clauses : 1. Defining (no commas) — the clause is necessary to identify the noun: The boy who won the race is my friend. (which boy? — essential info) 2. Non-defining (with commas) — extra information, can be removed: My brother, who lives in Dakar, is a doctor. (we already know which brother) ⚠️ In non-defining clauses, 'that' cannot replace 'who' or 'which'.
