What is an Adverbial Clause?
An adverbial clause is a group of words which plays the role of an adverb which contains a subject and a verb. When the complete dependent clause functions entirely as an adverb, that is, it modifies a verb, an adjective, or another adverb in the main clause, it is known as an adverbial clause. It is most often introduced to the main clause by the use of a subordinate conjunction, and just like other clauses, contains a subject as well as a predicate.
You can study the two sentences and the difference between an adverb and an adverbial clause.
1) Keep working on your weight loss program daily.
Daily= An Adverb
2) Keep working on your weight loss program until you lose five pounds of weight.
Until you lose five pounds of weight= an adverbial clause, which contains
- Until as the subordinate conjunction
- You as the subject
- Lose five pounds of weight as the predicate
And the whole of it works as an adverb to modify the verb (keep working) in the main clause.
An adverb clause will meet three requirements:
- It will contain a subject and verb.
- It will contain a subordinate conjunction that keeps the clause from expressing a complete thought.
- Finally, the clause answers one of these three adverb questions: How? When? Or Why?
Adverbial Clauses function as standard adverbs in a number of ways. They can be categorized into various types according to the following parameters:
1) Place or Location
The adverbial clauses that indicate place or location of action/verb in the main clause usually start with one of these subordinate conjunctions- where, wherever.
The adverbial clauses that indicate time of action/verb in the main clause usually start with one of these subordinate conjunctions- since, while, until, after, before, when, whenever, etc.
The adverbial clauses that indicate manner of action/ verb usually in the main clause start with one of these subordinate conjunctions- like, as, as if, etc.
The adverbial clauses that indicate reason of action/ verb in the main clause usually start with one of these subordinate conjunctions- because, as, in order to, since, so that etc.
5) Degree or Comparison
The adverbial clauses that indicate degree or comparison of verb in the main clause usually start with one of these subordinate conjunctions- as, than, etc. Though most adverbial clauses modify verbs, however these adverbial clauses of comparison may often modify adjectives and adverbs in the main clause as well.
6) Possibility or Conditionality
The adverbial clauses that indicate possibility or conditionality in the main clause usually start with one of these subordinate conjunctions- though, although, unless, if, even if, etc.
