Noun Clauses as Subjects & Objects
Learn how entire clauses can act as the subject or object of a sentence.
What is a noun clause?
A noun clause is a group of words with its own subject and verb that acts like a noun. It can be the subject or object of the main sentence — replacing a simple noun or pronoun.
Four types of noun clause
Word order inside the noun clause
Unlike direct questions, noun clauses use statement word order — the subject comes before the verb. There is no inversion.
Do you know where he works? ✓ | Do you know where does he work? ✗
Noun clauses as subjects — using "it" to delay
