Noun Clauses (n-cl)

Noun clauses are clauses that can function as nouns, in other words, as subjects, objects, or adjective complements.  Here are a few examples:

    1.  What she told me worried me.  (Subject)
    2.  I thought that she was making a mistake.  (Object)
    3.  She didn't know if she was right.  (Object)

As you can see, noun clauses usually begin with a WH-word, such as what, where, etc., with "that," or with "if."

This type of clause is usually still a problem even for advanced students, so it would be wise to study the first link below and then study the explanations and do the exercises that follow.
