What Are Conjunctions?

Conjunctions are words that join other words, phrases, or clauses together. They are essential for creating varied, flowing sentences and for showing the logical relationships between ideas β€” such as cause and effect, contrast, or condition.

The Three Types of Conjunctions

1. Coordinating Conjunctions (FANBOYS)

These join two equal grammatical elements β€” two nouns, two phrases, or two independent clauses.

ConjunctionUseExample
ForReason (formal)She left, for she was tired.
AndAdditionHe sings and dances.
NorNegative alternativeShe doesn't eat meat, nor does she eat fish.
ButContrastI tried, but I failed.
OrAlternativeTea or coffee?
YetContrast (surprising)She was tired, yet she kept going.
SoResultIt rained, so we stayed in.

Comma rule: When joining two independent clauses, place a comma before the coordinating conjunction: She studied hard, but she needed more time.

2. Subordinating Conjunctions

These introduce a dependent (subordinate) clause and connect it to the main clause. They show relationships such as time, cause, condition, and contrast.

RelationshipExamples
Timewhen, while, after, before, until, since
Cause/Reasonbecause, since, as
Conditionif, unless, provided that
Contrastalthough, though, even though, whereas
Purposeso that, in order that

Examples:

  • She stayed inside because it was raining.
  • Although he was nervous, he gave a great speech.
  • I will help you if you ask nicely.

Comma rule: When the dependent clause comes first, use a comma after it: Before she left, she said goodbye.

3. Correlative Conjunctions

These are pairs of conjunctions that work together to connect balanced elements.

PairExample
both ... andBoth the cat and the dog are friendly.
either ... orEither she wins or she learns.
neither ... norNeither snow nor rain stopped them.
not only ... but alsoShe is not only smart but also kind.
whether ... orI don't know whether to stay or go.

Agreement rule: With either/or and neither/nor, the verb agrees with the nearest subject: Either the students or the teacher is responsible.

Worked Examples

Combining sentences using conjunctions:

Original: She was tired. She finished the project.

  • Coordinating: She was tired, yet she finished the project.
  • Subordinating: Although she was tired, she finished the project.

Original: He did not eat breakfast. He did not eat lunch.

  • Correlative: He ate neither breakfast nor lunch.

Common Mistakes

  • Comma splice: Joining two independent clauses with only a comma: "I was late, I missed the bus" β€” add a conjunction or use a full stop.
  • Starting sentences with and/but: Acceptable in modern writing, but avoid it in formal essays.
  • Neither/nor confusion: "Neither the cat or the dog" is wrong β€” use "neither ... nor."
  • Missing comma before coordinating conjunctions when joining independent clauses.

Tips and Tricks

  • Use FANBOYS to remember the 7 coordinating conjunctions: For, And, Nor, But, Or, Yet, So.
  • Subordinating conjunctions make your writing more sophisticated β€” use them to show cause (because), contrast (although), and condition (if/unless).
  • Correlative conjunctions must be parallel: "She is both talented and hardworking" β€” both elements are adjectives.
  • Vary your conjunctions: overusing and makes writing feel flat.

Using Conjunctions to Vary Your Writing

Skilled writers use all three types of conjunction to create varied, sophisticated sentences. Here is how to upgrade simple writing with conjunctions:

Simple (no conjunctions): She was nervous. She gave a speech. The audience clapped.

With coordinating conjunction: She was nervous, but she gave a speech, and the audience clapped.

With subordinating conjunction: Although she was nervous, she gave a speech. Because she spoke clearly, the audience clapped.

With correlative conjunction: Not only did she overcome her nerves, but she also delivered a compelling speech.

Using a mix of conjunction types creates rhythm and shows the relationships between ideas clearly β€” essential for strong essay and creative writing.
