An adverbial clause is a dependent clause that functions as an adverb, providing information about the time, place, condition, manner, or reason related to the action in the main clause. This type of clause enhances the meaning of a sentence by answering questions like 'when?', 'where?', 'why?', or 'how?'. It is connected to finite clauses and can only exist alongside an independent clause, establishing a relationship through subordinating conjunctions to create complex sentences.
