What is Noun Clause?
A noun clause is a dependent clause that functions in a noun position, such as the subject, object, subject complement, or object of a preposition within a larger sentence.
What good noun clause looks like
Accurate noun-clause use depends on recognizing the clause as one grammatical unit, keeping embedded-question word order correct, and avoiding unnecessary that-clauses when a more direct noun or verb is clearer.
- Find the clause introduced by words such as that, what, whether, why, how, who, or whoever.
- Test whether the whole clause occupies a noun-like slot.
- Keep statement word order inside embedded questions rather than reverting to direct-question inversion.
- Revise heavy noun clauses when they obscure the main action.
