What Are Subordinate Clauses?

English has two kinds of clauses: subordinate (or dependent) and independent. The difference between them is that an independent clause can stand alone and a dependent one cannot. A subordinate clause by itself is a sentence fragment.

Complete stand-alone sentence: I want the ice cream that is made with soy instead of milk and cream.
Independent clause: I want the ice cream
Subordinate clause: that is made with soy instead of milk and cream


The subordinate clause depends on the independent clause to finish its meaning. The independent clause does not need the subordinate clause to properly function; rather, it benefits from the extra information that the subordinate clause provides.

Signals of Subordinate Clauses

Consider the following sentences and notice what they share in common:

Since I started exercising, I have noticed that I've been sleeping better at night.
Joanne is the mayor who can get things done for the best of the city.
Wherever Joseph decides to put that old rake is okay with me.


Each sentence includes a word that serves as a signal that a dependent thought is being expressed. The word is either a relative pronoun or a subordinating conjunction, and it subordinates the clause it is in.

From there, we can examine whether each subordinate clause is serving as a noun, an adjective, or an adverb. Let's look at the same sentences again to determine how the subordinate clauses are functioning.

Since I started exercising, I have noticed that I've been sleeping better at night.
Joanne is the mayor who can get things done for the best of the city.
Wherever Joseph decides to put that old rake is okay with me.


In the first sentence, since I started exercising modifies the verb phrase, have noticed, to describe the timing of the action. This makes the subordinate clause an adverb.

In the second sentence, who can get things done for the best of the city modifies mayor by further describing the noun. This makes the subordinate clause an adjective.

In the last sentence, the entire dependent clause wherever Joseph decides to put that old rake acts as the sentence subject. This makes the subordinate clause a noun.

The following table includes common signals of subordination. When you read or write them, be aware of their potential presence and function within a subordinate clause.

Relative Pronouns Subordinating Conjunctions
that whoever after as though in order that though whenever
what whom although because since unless where
which whomever as before so that until wherever
who whose as if if that when while


Subordinate Clauses: More Examples

To further solidify our understanding of what subordinate clauses are, we'll review a few more ways of how they operate in writing.

Subordinate Clauses as Nouns
I am unsure of when they will arrive. (object of a preposition)
Do you know when they will arrive? (direct object)
That they will arrive is certain. (subject)



Subordinate Clauses as Adjectives
Walter is a man who tries to live a virtuous life. (describes man)
Walter is a man whom we have always looked up to. (describes man)
Walter has always been someone whose virtues I admire. (describes someone)



Subordinate Clauses as Adverbs (*each sentence describes the timing of the action)
We will clean up after the guests leave.
When the guests leave, we will clean up.
We will clean up whenever the guests leave.

The Blue Book of Grammar and Punctuation


by Lester Kaufman and Jane Straus

Revised and Expanded Blue Book of Grammar and Punctuation Now Available!

The twelfth edition of The Blue Book of Grammar and Punctuation made its debut on May 4, 2021. It has been seven years since the eleventh edition was published. So when the publisher, Jossey-Bass, requested another go-round, the team at GrammarBook.com was elated.

You will find the new, extensively revised and expanded version in keeping with our consistent vision of a direct, concise, unfussy grammar book.

The Blue Book, which started life as a booklet for California state employees, has now sold hundreds of thousands of copies. Over the years, we’ve seen the number of subscribers to our weekly newsletter grow from dozens to scores to hundreds; now, there are over 40,000 of you worldwide.

The new edition continues to stress the difference between rules on the one hand and conventions, customs, and tendencies on the other. We also added previously uncovered material, such as irregular verbs, that have been popular topics in our newsletters and blogs. In addition, the Confusing Words and Homonyms section has been greatly expanded, and we have developed all-new quizzes covering even more topics.

The new Blue Book takes on English in all its often maddening complexity, acknowledging its quirks, gray areas, exceptions, limitations, and contradictions. We realize that people want straight answers, but with English, there sometimes aren’t any, and we would be remiss in saying otherwise.
