How It Works
Meaning
Noun clauses are dependent clauses that function as nouns within a sentence. They often begin with words like that or whether and can express statements, questions, or uncertainty.
These clauses are used to report information, beliefs, or decisions without asking direct questions. At the B2 level, mastering noun clauses helps in constructing complex sentences for clearer communication.
Use it when
- Reporting information or beliefs, using that.
- Expressing uncertainty or yes/no questions, using whether.
