Adjective Clauses
Adjective clauses ( relative clauses) are types of subordinate clauses that act as adjectives. The whole clause does the job of an adjective.
Relative pronoun introduce relative clauses Most of the time, relative clauses are introduced by relative pronouns who, whom,whose, that, which Here are examples using these relative pronouns: 1. The person who made the mess needs to clean it ( modifying the person) 2. The person whom you teach is my sister. ( modifying girl)
Relative pronoun introduce relative clauses 3. people whose cats shed need to vacuum often. ( modifying people) 4. This is the house that Ali built. ( modifying house) 5. The book which I had not read fell on the floor. (modifying book)
No relative pronoun Sometimes the relative pronoun is missing from the relative clause. We can still have an adjective clause without the relative pronoun. The instrument that I love is the piano. Or: The instrument I love is the piano.
Relative Adverbs While most of the time relative clauses are introduced by relative pronouns, sometimes they are introduced by relative adverbs ( where, when, why) This is the park where we played. Tuesday is the day when we have pizza for dinner. Our teacher told us the reason why we study grammar.
