Adverbial Subordinate Clauses

Complex Clauses


Adverbs are expressions that function as modifiers to other elements in the clause. They can provide a wide range of information. {see Adverbs of Frequency, A1 Level}

Adverb clauses are words combination that act like an adverb.


We form adverbial clauses by using adverbs.

Adverbial clauses can go before or after main clauses.

We divide adverb clauses from other sentences by a comma (,).


  • Wherever there is a clinic, there will be doctors as well.
  • Wherever I go, I meet people that I know.
  • He underwent surgery in order to remove the cancer.
  • If you run too fast, you will twist your ankle.


We use adverb clauses to give information about time, place, purpose, and cause of an action.

We use different adverbs for different information:

  • Time: after, as soon as, before, by the time, once, soonuntil, when, whenever, while;
  • Place: here, there, wherever;
  • Purpose: as a result, consequently, hence, in order to, thereforethus;
  • Cause of an action: as, as much as, because, if, since.
