Relative clauses
- who (people), which (things), that (both), whose (possession), where (place).
- The man who called is my uncle.
Conditionals
- Zero/first/second/third as cause-and-result structures.
Key idea
Relative clauses add information using who/which/that; conditionals link a condition to its result.
Remember
Use 'whose' to show possession in a relative clause.
