An adverbial clause is a dependent clause that performs the function of an adverb. It modifies a verb, adjective, or another adverb by telling us when, where, why, how, under what condition, or to what extent something happens.
Structure 👇
An adverbial clause usually contains:
▫️a subject
▫️a verb
▫️a subordinating conjunction
Common subordinating conjunctions include because, although, if, when, since, while, after, before, unless, until, and so that.
Types of Adverbial Clauses
1. Adverbial Clause of Time – tells us when something happens
▫️When the rain stopped, we went outside.
▫️We waited until the teacher arrived.
2. Adverbial Clause of Reason – tells us why something happens
▫️She stayed home because she was sick.
▫️Since it was late, we went home.
3. Adverbial Clause of Condition – tells us the condition under which something happens
▫️If you study hard, you will pass.
▫️We will go out unless it rains.
4. Adverbial Clause of Contrast – shows an opposing idea
▫️Although he was tired, he finished the work.
▫️She continued working even though she was sick.
5. Adverbial Clause of Purpose – tells us why something is done
▫️She studies hard so that she can succeed.
6. Adverbial Clause of Place – tells us where something happens
▫️Sit wherever you like.
7. Adverbial Clause of Manner – tells us how something happens
▫️He behaved as if he knew everything.
Important Point 👇
An adverbial clause cannot stand alone as a complete sentence because it is a dependent clause.
For example:
❌ Because she was sick.
This is incomplete.
✅ She stayed home because she was sick.
When an adverbial clause comes before the main clause, we normally use a comma:
▫️Because it was raining, we stayed indoors.
When it comes after the main clause, a comma is usually unnecessary:
▫️We stayed indoors because it was raining.
