Adverb clauses are an important part of spoken and written English, and must be understood if a student wants to be a fluent speaker or a better writer.
A clause is a unit of grammar that expresses a proposition. In other words, it is part of a sentence that contains some form of meaning:
Although there was a storm, I walked to work. Here, there are two clauses. “Although there was a storm” expresses a proposition, and so does “I walked to work.” The first clause in the example is called an adverb clause, which means that it is part of a sentence that contains a subordinating conjunction, a subject, and a verb. There are essentially five types of adverb clauses, and they can use a variety of subordinating conjunctions. They are:
1. Place – wherever
, anywhere
, everywhere
, where
Everywhere she goes, she brings a camera.
2. Time – since
, while
, as soon as
, before
, after
, until
, when
, anytime
While we were waiting for the pizza guy to arrive, we played poker at the kitchen table.
3. Reason – because
, since
, as
, for
, so that
Because it was exceptionally cold, I wore my winter jacket.
4. Condition – if
, when
, unless
, even if
, even though
Even if they lose by five goals, people will still love them.
5. Contrast – though
, although
, despite
, in spite of
, whereas
Despite the poor service provided by the wait staff, we still enjoyed the food and the atmosphere of the restaurant.
All of these examples contain two parts: a subordinate clause (the adverb clause), and an independent clause. A subordinate clause needs an independent clause for it to have a complete context and for it to make sense.
The subordinate clause and independent clause can be reversed in a sentence. However, if the subordinate clause comes first, there must be a comma between it and the independent clause:
Anytime I want to go outside, it always seems to rain.
This sentence can also be flipped, so that the independent clause comes first. However, if the independent clause comes first, a comma is not necessary:
It always seems to rain anytime I want to go outside.
