Noun Clauses
Noun clauses perform the same function in sentences that nouns do. They can be the subject (What Billy did shocked his friends), the object of a verb (Billy’s friends didn’t know that he couldn’t swim.) , the subject complement (Billy’s mistake was that he refused to take lessons.), the object of the preposition (Mary is not responsible for what Billy did.), or an adjective complement (Everybody is sad that Billy drowned.)
