Ultimate Subordinate Clause Guide: Everything You'll Need

Main Subordinate Clause Takeaways:

• A subordinate clause contains a noun and a verb.
• This type of clause is also called a dependent clause since it doesn’t make sense by itself.
• One easy trick for remembering the difference is to look at the prefix (“sub” means under or below).
• On the other hand, independent clauses do make sense by themselves. In fact, they work as stand-alone sentences (not “sub” or below any other clause).
• As a part of speech, subordinate clauses can be nouns, adverbs, and adjectives.
• Subordinating conjunctions connect subordinate clauses with main clauses. Examples include because, while, and although.
• You can start a sentence with a subordinating clause.

In this guide, we’ll dive into just one type of clause: the subordinate clause.

What is a Main and Subordinate Clause?

Main and subordinate clauses are the building blocks of all sentences. First, a main clause can stand alone as a complete sentence. In fact, it’s also called an independent clause since it doesn’t depend on another clause to make sense. However, a subordinate clause does depend on another clause in order to mean something (it’s subordinate to the main clause). Therefore, a main clause can be a complete sentence without another clause but a subordinate clause cannot. Join the two types of clauses with a subordinating conjunction like but, while, or because.

What is a Subordinate Clause and What are Some Examples?

Subordinate clauses are also be called dependent clauses because they depend on the main clause to have meaning. While they contain a subject and a verb, but they cannot stand alone as a complete sentence (Example: Because the dog ate it; noun = dog; ate = verb). In other words, a main clause can make sense without another clause, but a subordinate clause doesn’t make sense without a main clause. Instead, they add information to main clauses (I wasn’t able to bring my famous apple pie because the dog ate it).

Here are more subordinate clause examples:

Can you Start a Sentence With a Subordinate Clause?

You can start a sentence with a subordinate clause (Since I was up early, I decided to go for a long walk). Or, it can go later in the sentence (I decided to go for a walk since I was up early). Other than the position of the clause, you’ll notice that the main difference between these two constructions is a comma; If the subordinate clause comes at the beginning of the sentence, you need to place a comma after it. However, if the subordinate clause comes later, you don’t need a comma with this clause.

[/correct]While she cooks, my mother loves to play high-energy music.[/correct]

[/correct]My mother loves to play high-energy music while she cooks.[/correct]

Do you put a Comma Before a Subordinate Clause?

You don’t need to put a comma before a subordinate clause (We love cooking with garlic even though it’s an intense flavor). However, when it comes at the beginning of sentence, you do need a comma after the subordinate clause (Even though it’s an intense flavor, we love cooking with garlic).

How do you Identify a Subordinate Clause in a Sentence?

To identify a subordinate clause in a sentence, look for a clause that 1) starts with a subordinating conjunction (like because, while, and considering) or a relative pronoun (like who, whoever, whenever); 2) contains a noun and a verb; 3) doesn’t form a complete sentence. They can appear at the beginning or later on in a sentence, but subordinate clauses always have a few key elements in common.

Subordinate clauses are easy to spot. They begin with subordinating conjunctions or dependent pronouns (also called relative pronouns), and they contain both a subject and a verb. Instead of forming complete sentences by themselves, subordinate clauses contribute information to main (or independent) clauses.

The subordinating conjunction and dependent pronouns in all the following examples of subordinate clauses are bold to make them easier to spot.

First, you’ll see the subordinate clause example. Then, we’ll join this example with an independent clause to form a full sentence.

What are the 3 Subordinate Clauses?

The three types of subordinate clauses are: noun, adverb and adjective clauses. This basically means that we can treat a subordinate clause as an entire unit of a sentence rather than just a noun and verb pieced together. When we do, this entire unit can act as a noun, adverb, or even an adjective.

For instance, when a subordinate clause is the subject, direct object, prepositional object, or predicate nominative, its a noun clause. Similarly, when it modifies verbs, adverbs, and adjectives, it’s an adverb clause. Finally, when it modifies nouns and pronouns, it’s an adjective clause.

How do you use Subordinate Clause in a Sentence?

Use a subordinate clause in a sentence to provide more information or details about the main clause. They don’t make sense by themselves. They need a buddy — a main clause — to become part of a sentence. Connect a subordinate clause with a main clause using either a subordinating conjunction (while, although, since) or a dependent pronoun, like this:

In each example, the subordinate clause tells us why the main clause happens, or to whom or what the main clause applies.

Does a Subordinate Clause Need a Verb?

Subordinate clauses need a noun and a verb. What’s more, they also need an independent, or main, clause to make sense. This means that even though a subordinate clause contains a noun and a verb, it can’t make a complete sentence without a main clause.

What is a Subordination Clause?

A subordination clause is not the same thing as a subordinate clause. One one hand, a subordination clause is a contractual provision that gives one claim on a debt precedence over other claims that come later. This type of legal clause usually appears in mortgage refinancing agreements. On the other hand, a subordinate clause is a clause comprised of a noun and a verb. Unlike an independent clause, subordinate clauses cannot stand alone as a sentence.

While there is some conceptual overlap, there is a clear difference between the meanings and the usages of these words. For example, associate a subordination clause with other debts being subordinate to the main one.

Similarly, associate subordinate clause with a clause being subordinate to the main one.

There may be four different types of sentences: simple, compound, complex and compound-complex, but they all have one thing in common; they’re all made of clauses.

Some sentences contain just one independent clause, while others feature both independent and dependent clauses.
