Conjunctive adverb is an adverb or adverbial phrase that indicates a relation in meaning between two sequential independent clauses (or main clauses). It is also called a conjunct, a transitional conjunction, or a cohesive conjunction.
subordinate adverbial clauses function within sentences as adverbs. Just as most adjective clauses begin with a relative pronoun, adverb clauses always begin with a subordinating conjunction (after, before, unless, although, when, while, as soon as, as long as, as if, where etc) marking them as grammatically subordinate Hope this helps
