Noun Clause

Noun clause is a clause (ie subject and verb) that functioned as a noun. Noun clause in the sentence is generally used as subject and object of the sentence.

Noun clause can be preceded by:

     * Question word or relative pronoun in the form of a single question word or phrase:
           - Single question word (ie Pls, how, what, ect.).
           - Question word + determiner / noun / adjective / adverb.
           - Question word + infinitive.
     * conjunction (i.e. whether and if).
     * That or the fact that.

So the pattern of the noun clause is:

Question words / conjunction / That + subject + verb + ...

examples:
