What is a noun clause?
What is the syntax, or form, of a noun clause?

     WH-WORD SUBJECT VERB PHRASE  (WH SUB VP)
It is a sentence, or clause, which acts like a single noun, usually an object or a subject of a sentence.

Samples:

What is her name?    
→     I don't know what her name is.

Who has Abdullah's phone number?    
→     Let me find out who has Abdullah's phone number.

When is our next test?    
→     I'm not sure when our next test is.

Where are we meeting this afternoon?    
→     We haven't decided where we are meeting yet.

Why didn't he call me?    
→     He didn't tell me why he didn't call you.

Noun Clauses

What WH-words can be used in a noun clause?

     who, what, where, when, why
   
     which N, what N, whose N, how Adj

     if / whether

     that


The following WH-words cannot stand alone.  Consider the noun (N) or adjective (Adj) to be part of the WH-word and not a subject or object when you are constructing a noun clause.  For example, in the sentence I wonder whose car this is, the WH-word is whose car, the subject is this, and the verb phrase is is.

     WHICH N:  Do you remember which flavor he wanted?

     WHAT N:  Can you tell me what time it is?

     WHOSE N:  Does anyone know whose phone this is?

     HOW Adj:  Would you help me figure out how much water I should bring?

The following WH-words are used in response to Yes/No questions.  Both if and whether mean the same thing, so either one is correct.  Do not use that.

     Can they come to the party?    
→     I don't know if they can come to the party.

     Has she been to Paris?    
→     I don't know if she has been to Paris.

     Does he like spicy food?    
→     I have no idea if he likes spicy food.

Students often wonder when it is appropriate to use the WH-word that.  My answer is that WH-word that can be used only when none of the other WH-words are possible.  Additionally, when there is no doubt or question involved in what you are saying, that is probably the WH-word that you need to use.

    
Can they come to the party?    
→     They told me that they could come to the party.

     Has she been to Paris?    
→     I think that she went to Paris five years ago.

     Does he like spicy food?    
→     I believe that he dislikes spicy food.

As you can see above, what you say before the noun clause is important when deciding whether or not to use the WH-word that.  If you look through chapter 14, you will see a list of verbs that are typically followed by that-clauses, as they are called.  Note the meaning of those verbs.  You will see that there is a sense of knowing something rather than not knowing.
