Definition of Independent Clause
An independent clause, also known as a main clause, is a group of words that contains a subject and a verb and expresses a complete thought. Because it expresses a complete thought, an independent clause can stand alone as a sentence.
This is the fundamental difference between an independent clause and a dependent clause, which cannot stand alone as a sentence.
The primary function of an independent clause is to convey information or express an idea in a grammatically complete manner. It forms the backbone of simple sentences and serves as a building block for more complex sentence structures.
Understanding independent clauses is crucial for constructing clear, concise, and grammatically correct sentences.
In essence, an independent clause is the simplest form of a sentence. It contains all the necessary elements to be considered a complete statement.
Without an independent clause, a sentence would be incomplete and grammatically incorrect. Recognizing and using independent clauses correctly is essential for effective written and spoken communication.
Structural Breakdown
The basic structure of an independent clause consists of two essential components: a subject and a predicate. The subject is the noun or pronoun that performs the action or is being described. The predicate contains the verb, which expresses the action or state of being, and any objects or complements that complete the thought.
Let’s break down the structure further. The subject usually comes before the verb, although there are exceptions, such as in questions or sentences beginning with adverbs.
The predicate always includes the verb and may also include direct objects, indirect objects, and subject complements, depending on the type of verb used.
Here’s a visual representation of the structure:
Subject + Verb (+ Object/Complement) = Independent Clause
Consider the following examples:
- The dog barked. (Subject: The dog; Verb: barked)
- She reads books. (Subject: She; Verb: reads; Object: books)
- They are happy. (Subject: They; Verb: are; Complement: happy)
Each of these examples contains a subject and a verb and expresses a complete thought. Therefore, each is an independent clause and can stand alone as a sentence.
Subject
The subject of an independent clause is the noun or pronoun that performs the action or is being described. It answers the question “Who?” or “What?” is performing the verb.
The subject can be a single word or a phrase.
Examples:
- John ran.
- The old car broke down.
- They are coming.
Predicate
The predicate of an independent clause contains the verb and any other words that complete the thought. It tells what the subject does or is.
The predicate always includes the verb and may also include objects, complements, and modifiers.
Examples:
- John ran.
- The old car broke down.
- They are coming to the party.
Types of Independent Clauses
While all independent clauses share the same basic structure, they can be categorized based on their function and the types of verbs they contain. Understanding these different types can help you construct more varied and interesting sentences.
Declarative Clauses
Declarative clauses make a statement. They are the most common type of independent clause and simply convey information.
Examples:
- The sun is shining.
- She likes coffee.
- They live in London.
Imperative Clauses
Imperative clauses give a command or make a request. The subject is usually implied (you).
Examples:
- Close the door. (Implied subject: You)
- Please be quiet. (Implied subject: You)
- Do your homework. (Implied subject: You)
Interrogative Clauses
Interrogative clauses ask a question. They usually begin with an auxiliary verb or a question word (who, what, where, when, why, how).
Examples:
- Are you coming?
- What is your name?
- Where do you live?
Exclamatory Clauses
Exclamatory clauses express strong emotion or surprise. They often begin with “What” or “How.”
Examples:
- What a beautiful day!
- How exciting this is!
- What a surprise!

Usage Rules
Using independent clauses correctly involves understanding several key rules. These rules ensure that your sentences are grammatically sound and convey your intended meaning effectively.
Subject-Verb Agreement
The verb in an independent clause must agree in number with its subject. This means that if the subject is singular, the verb must be singular, and if the subject is plural, the verb must be plural.
Examples:
- The dog barks. (Singular subject, singular verb)
- The dogs bark. (Plural subject, plural verb)
- She is happy. (Singular subject, singular verb)
- They are happy. (Plural subject, plural verb)
Punctuation
When an independent clause stands alone as a sentence, it should end with a period, question mark, or exclamation point, depending on its function (declarative, interrogative, or exclamatory).
Examples:
- The sun is shining. (Declarative)
- Are you coming? (Interrogative)
- What a beautiful day! (Exclamatory)
Coordination with Conjunctions
Independent clauses can be joined together to form compound sentences using coordinating conjunctions (for, and, nor, but, or, yet, so). A comma is usually placed before the coordinating conjunction.
Examples:
- The sun is shining, and the birds are singing.
- She likes coffee, but he prefers tea.
- They are tired, so they are going to bed.
Semicolon Usage
Independent clauses can also be joined together using a semicolon. This is often used when the clauses are closely related in meaning.
Examples:
- The sun is shining; it is a beautiful day.
- She likes coffee; it helps her stay awake.
- They are tired; they need to rest.
Conjunctive Adverbs
Independent clauses can be joined using a conjunctive adverb (e.g., however, therefore, moreover, furthermore, nevertheless). A semicolon is placed before the conjunctive adverb, and a comma is placed after it.
Examples:
- The sun is shining; however, it is still cold.
- She likes coffee; therefore, she drinks it every morning.
- They are tired; moreover, they have a lot of work to do.
Common Mistakes
Even experienced writers sometimes make mistakes when using independent clauses. Being aware of these common errors can help you avoid them in your own writing.
Run-On Sentences
A run-on sentence occurs when two or more independent clauses are joined together without proper punctuation or conjunctions. This can make the sentence difficult to read and understand.
Incorrect: The sun is shining the birds are singing.
Correct: The sun is shining, and the birds are singing.
Correct: The sun is shining; the birds are singing.
Comma Splices
A comma splice occurs when two independent clauses are joined together with only a comma. This is a common error that can be easily avoided by using a coordinating conjunction or a semicolon.
Incorrect: The sun is shining, the birds are singing.
Correct: The sun is shining, and the birds are singing.
Correct: The sun is shining; the birds are singing.
Fragmented Sentences
A sentence fragment is an incomplete sentence that does not contain an independent clause. It may be missing a subject, a verb, or both, or it may not express a complete thought.
Incorrect: Because it was raining.
Correct: Because it was raining, we stayed inside.
Correct: It was raining.
Lack of Subject-Verb Agreement
Failing to ensure that the verb agrees with the subject in number is a common error that can detract from the clarity of your writing.
Incorrect: The dog bark.
Correct: The dog barks.
Incorrect: They is happy.
Correct: They are happy.
