I understand that "that" can be either a relative pronoun or a subordinating conjunction, I just don't understand when. I know that both of these create dependent clauses, and I am pretty sure that subordinating conjunctions create adverb clauses (is this the same as the conjunction functioning as an adverb?) and that relative pronouns create noun and adjective clauses (again, is this the same as saying that the relative pronoun functions as a noun and an adjective?). I have been recently been working on doing some sentence analysis (breaking down a sentence into its constituent word forms and functions), and I have been told to bracket off the dependent clause that the relative pronoun starts in order to find its function. However, this is much more difficult to do with "that", since I don't know how to find out whether "that" is a relative pronoun or a conjunction, and I then don't know how to decide the function for the conjunction or relative pronoun of "that".
