Adverbial clauses are subordinate clauses that function as adverbs, modifying verbs, adjectives, or other adverbs. They typically begin with a subordinating conjunction, such as "because," "although," "when," "if," or "since," and contain a subject and a verb. These clauses provide information about time, place, manner, reason, purpose, condition, concession, or contrast, adding depth and complexity to the main clause.
