Adjective Clause / Relative Clause

Point 1: A defining relative clause is like an adjective. It gives important information that describes or identifies the noun.
  1. This is the shirt that I got on sale.
  2. This is the house that had the party.
  3. The class that I took is no longer offered at the school.
  4. Do you know someone who speaks French?
Point 2: We use that and which in defining clauses with nouns (things and places). These words are often used to connect the noun to extra information.
  1. The car that I just bought is really fast.
  2. The cafe that I usually go to is closed today.
  3. The town that I grew up in is not the same anymore.
  4. The dog which lives over there is very scary.
Point 3: We use that and who in defining clauses with people. In these sentences, no extra subject is needed in the relative clause.
  1. I know a guy that owns his own island.
  2. I know a guy who owns his own island.
  3. I only date people that don't smoke.
  4. I only date people who don't smoke.
Point 4: When the noun is the same as the subject in the relative clause, you omit the subject.

Point 5: When the noun is the same as the object in the relative clause, you omit the object.
  • I bought a hat that wear on sunny days.
    • I bought a hat. I wear it on sunny days.
