Understanding Clauses in Sentences
1. What Is a Clause?
A clause is a group of words that contains:
- A subject
- A verb
Clauses can be complete thoughts or incomplete thoughts, and this distinction determines whether they can stand alone as sentences.
There are two main types:
- Independent clauses
- Dependent clauses
Understanding the difference is essential for building simple, compound, complex, and compound‑complex sentences.
2. Independent Clauses
An independent clause is a clause that:
- Has a subject
- Has a verb
- Expresses a complete thought
- Can stand alone as a sentence
Examples
- The player scored.
- The update launched today.
- The fans reacted instantly.
- The article went viral.
Independent clauses are the foundation of all sentence structures.
A. What Independent Clauses Do
Independent clauses allow writers to:
1. Deliver clear, direct information
The team won.
2. Build compound sentences
The team won, and the fans celebrated.
3. Anchor complex sentences
Although the team struggled, they won the game.
4. Improve SEO
Google favors:
- Clear subjects
- Clear verbs
- Complete thoughts
Independent clauses check all three boxes.
B. How to Identify an Independent Clause
Ask:
- Is there a subject?
- Is there a verb?
- Does it express a complete thought?
- Can it stand alone as a sentence?
If yes → independent clause.
3. Dependent Clauses
A dependent clause (also called a subordinate clause):
- Has a subject
- Has a verb
- Does NOT express a complete thought
- Cannot stand alone
- Must be attached to an independent clause
Dependent clauses begin with subordinating conjunctions or relative pronouns.
Examples
- because the server crashed
- when the trailer dropped
- although the player was injured
- which fans loved
- who scored the goal
These are incomplete thoughts — they need an independent clause to make sense.
A. Types of Dependent Clauses
1. Adverb Clauses
Modify verbs, adjectives, or other adverbs.
Begin with subordinating conjunctions.
Examples:
- because the update failed
- when the game ended
- although the weather was terrible
2. Adjective (Relative) Clauses
Modify nouns.
Begin with relative pronouns.
Examples:
- who scored the goal
- that users reported
- which fans loved
3. Noun Clauses
Act as subjects, objects, or complements.
Examples:
- what the coach said
- why the app crashed
- how the team won
B. How to Identify a Dependent Clause
Ask:
- Does it start with a subordinating conjunction or relative pronoun?
- Does it have a subject and verb?
- Does it express an incomplete thought?
- Can it stand alone? (If no → dependent clause)
4. Subordinating Conjunctions & Relative Pronouns
These words signal dependent clauses.
Common Subordinating Conjunctions
because, although, since, when, while, after, before, until, unless, if, as, even though, once
Common Relative Pronouns
who, whom, whose, which, that, where, when
Writers must recognize these instantly.
5. Why Clauses Matter in Professional Writing
Clauses determine sentence structure, which determines:
A. Clarity
Clear clauses → clear sentences → clear articles.
B. SEO Strength
Google rewards:
- Clean syntax
- Logical relationships
- Strong subjects and verbs
C. Tone & Professionalism
Clauses help writers control:
- Pacing
- Emphasis
- Flow
- Complexity
D. Avoiding Errors
Most grammar mistakes come from misusing clauses:
- Run‑ons
- Fragments
- Comma splices
- Misplaced modifiers
Mastering clauses eliminates these issues.
6. Examples in Real Article Writing
Independent Clause Example

Another Example
