A relative pronoun makes a connection between an antecedent  an a subordinate clause that gives information about the  antecedent.   The relative pronouns are: who, whomâ¦, whose, which, that.    Examples:   The teacher who assigned the work should answer your  questions.
Clauses joined by coordination are called main clauses (or independent clauses). This is in contrast to subordination, in which a subordinate clause (for example, an adverb clause or an adjective clause) is attached to a main clause. Clausal subordination is often (but not always) indicated by a subordinating conjunction (in the case of adverb clauses) or a relative pronoun (in the case of adjective clauses). See Examples and Observations below. Also see: Complement Clause.
