Definition:

 A dependent clause used as an adverb within a sentence to indicate time, place, condition, contrast, concession, reason, purpose, or result. Also known asadverbial clause.

An adverb clause begins with a subordinating conjunction (such as if, when, because, or although) and usually includes a subject and a predicate.

Or we can define An adverbial clause (or an adverb clause) is a group of words which plays the role of an adverb. (Like all clauses, an adverbial clause will contain a subject and a verb.)

   
     For Examples:

      

      - Keep hitting the gong hourly.   (normal adverb)

      - Keep hitting the gong until I tell you to stop.  (adverbial clause)

       In the examples above, the normal adverb and adverbial clause both tell us when the gong is to be hit. They are both adverbs of time. 

 Observations:

        The name "adverbial" suggests that adverbial clauses modify verbs; but they modify whole clauses, as shown by the examples [below]. Their other key property is that they are adjuncts, since they are typically optional constituents in sentences. They are traditionally classified according to their meaning, for example adverbial clauses of reason, time, concession, manner or condition, as illustrated below.

a. Reason
    Because Marianne loved Willoughby, she refused to believe that he had deserted her.
b. Time
    When Fanny returned, she found Tom Bertram very ill.
c. Concession
    Although Mr D'Arcy disliked Mrs Bennet he married Elizabeth.
d. Manner
    Henry changed his plans as the mood took him.
e. Condition
    If Emma had left Hartfield, Mr Woodhouse would have been unhappy.
