Noun clause or Adejctive clause

Hi.
Her idea is that I hire you was a very fun one.
As I know it's a defining Relative Clause.

Thanks Fandorin,

Did you mean "is" was omitted in the sentence or you put it in there to demonstrate your point?

The grammar book I'm reading (I know, I know I'll throw it away as soon as I'm done with it) identified it as a Noun clause acted as an appositive to "her idea". Could you expound on your arguement? Thank you.

I'm sorry I made a mistake. Of course it's a Nominal Clause. I hurried up.

Her idea that I hire you was a very fun one.
It's kind of Subjunctive. And as I know only Present Tense can be used in Nominal Clause.
Her idea that I hire you is a very fun one.

Thanks Fandorin, "nominal" and "subjunctive" are 2 new terms I haven't learned, and I will look them up.

My first instinct said adjective clause (now you revised it to nominal clause, does it still full under adjective clause?) and decided that the book make an innocent mistake until I encountered other similiar questions with the same result:

Nominal Clause = Noun Clause. Adjective Clause = Relative Clause.
Don't mix up them.

Subjunctive is used when the action is not REAL or PREFFERED. And it's rarely used in contemporary English, in idiomatic expression or in more formal speech.
Relative clause (Subordinate Clause, Adjectival Clause ) is used when you want to give more information about event or person or thing is described in the sentence.

Don't worry. It could freak you out because there are a lot of pecularities in Grammar. Don't hurry up.

I'm freaking out! And I have to worry, there's a unmerciful sword of a test waiting for me to slit my throat at the first chance that I make a wrong move.

Somebody help me!

RaenHer idea that I hire you was a very funny one.

Would you say the clause I underlined is a Noun clause acts as an appositive to "her idea" or a Adjective Noun modifying the idea?

It's the first -- a noun clause -- an appositive to idea.
Her idea was a very funny one.
What was her idea?

Adjective clause is the same as a Relative clause, isn't it?
As I have caught the Nominal Clause is used when it performs the function of the noun, doesn't it?
Mary idea that I should buy a car is a very smart one. It's a Nominal Clause
The suggestion that he had better go makes everything clear - It's a Nominal Clause
The suggestion that I heard messes up all our
