What is the subordinate clause of the following sentence? is it a noun, adjective, or adverb clause?: Is this the book that your grandfather gave you for your birthday?
In general, it is an adjective clause starts by THAT. A subordinate clause.
Look; who, whom, whose, that and which these 5 connecting words make an adjective clause.
In addition these, how, however, what, whatever these types of connecting words make a noun clause too if they bear sub+verb ( at least)
Somewhere, many grammarians are disagree about a noun clause and adjective clause by 5 connecting words. They try to establish themselves as noun clauses too instead of adjective clause.
Like they assume "that" is an adjective and the rest whole clause is an object or complement! So it is noun clause of object that is modifying by That.
If you question, is this the book? Then adjective complement or object will be --that your grandfather gave you in your birthday.
Look, I make sure this is not an essay way to understand the noun clause immediately as it has a bit exception rule, but if ones practice them day day, it will clear to their minds, no short cut a way, here.
I give you the best authenticated but an essay a source of it here to go further if you are an inquisitive learner or forget as we many need not to learn in details too that I have been watching over my professional students for few years who many desperately need IELTS/TOEFL/GMAT scores.
