Coordinating conjunctions connect words, phrases, or clauses of the same grammatical type. The seven commonly taught coordinating conjunctions can be remembered with FANBOYS: For, And, Nor, But, Or, Yet, and So. They help writers express relationships such as addition, contrast, choice, reason, and result.
This guide explains how each coordinating conjunction works, when punctuation is required, and which common mistakes to avoid.
What are Coordinating Conjunctions?
Coordinating conjunctions join elements of equal grammatical status. These elements can include nouns, verbs, adjectives, phrases, or independent clauses. The conjunction signals how the coordinated elements relate while keeping their grammatical roles parallel.

Their primary function is to link these elements, providing a smooth transition and indicating the relationship between them. For example:
- Connecting Words: “She bought apples and oranges.”
- Connecting Phrases: “She worked in the morning and after lunch.”
- Connecting Clauses: “I wanted to go for a walk, but it started raining.”
The most commonly used coordinating conjunctions can be remembered with the mnemonic FANBOYS:
- For
- And
- Nor
- But
- Or
- Yet
- So
These conjunctions can signal relationships such as addition, contrast, choice, reason, or result. The precise relationship depends on both the conjunction and the surrounding context.
Using coordinating conjunctions accurately helps readers follow the structure and logic of a sentence.
The FANBOYS Conjunctions
The acronym FANBOYS represents the seven coordinating conjunctions commonly taught in English:

1. For
- Function: Introduces a reason or explanation.
- Usage: Similar in meaning to “because,” but generally more formal and used to connect two independent clauses.
- Example: “She took an umbrella, for it looked like it might rain.”
2. And
- Function: Adds one thing to another, indicating continuation or addition.
- Usage: Connects words, phrases, or clauses that are similar in nature.
- Example: “He enjoys reading and writing.”
3. Nor
- Function: Presents an additional negative idea.
- Usage: Used after a negative statement, introducing another negative element.
- Example: “She has never visited Asia, nor has she traveled to Africa.”
4. But
- Function: Shows contrast or exception.
- Usage: Connects ideas that are oppositional or contradictory.
- Example: “He is talented but lazy.”
5. Or
- Function: Offers an alternative or choice.
- Usage: Connects different possibilities or options.
- Example: “You can call me or send an email.”
6. Yet
- Function: Introduces a contrasting idea, often implying an unexpected outcome.
- Usage: Similar to “but,” often with an unexpected or surprising contrast.
- Example: “The team was inexperienced, yet they won the championship.”
7. So
- Function: Indicates effect, result, or consequence.
- Usage: Connects a cause with its effect.
- Example: “The cake was delicious, so I had a second slice.”
Understanding the typical function of each conjunction helps writers choose a connection that accurately represents the relationship between coordinated elements.
Rules for Using Coordinating Conjunctions
Correct conjunction use depends on what is being joined and whether each element is an independent clause. The following rules cover the most common patterns.

1. Connecting Independent Clauses
In standard edited English, place a comma before a coordinating conjunction when it joins two independent clauses.
Examples:
- ❌ “I wanted to go hiking but the weather was too cold.”
- ✅ “I wanted to go hiking, but the weather was too cold.”
2. Connecting Words or Phrases
When linking single words or phrases (not complete clauses), a comma is not needed.
Examples:
- “She likes apples and oranges.”
- “He enjoys chocolate, vanilla, and strawberry ice cream.”
3. Starting Sentences with Coordinating Conjunctions
Beginning a sentence with a coordinating conjunction is grammatically acceptable. It can emphasize a continuation, contrast, or result, but the words that follow should still form a complete sentence rather than a sentence fragment.
Examples:
- “But that’s not the only thing to consider when making a decision.”
- “And they lived happily ever after.”
4. Avoiding Comma Splices
A comma splice occurs when a comma joins two independent clauses without a coordinating conjunction. This is a common error and can make sentences confusing.
Examples:
- ❌ “She loves to paint, she is very talented.”
- ✅ “She loves to paint, and she is very talented.”
- ✅ “She loves to paint; she is very talented.” (using a semicolon)
5. Avoiding Run-on Sentences
A run-on sentence occurs when two or more independent clauses are joined without suitable punctuation or a valid connecting structure. A comma plus a coordinating conjunction is one way to repair the error; a period or semicolon may also work.
Examples:
- ❌ “I went to the market I bought some fruits I came back home.”
- ✅ “I went to the market, bought some fruits, and came back home.”
6. Balancing Parallel Elements
When using coordinating conjunctions, the elements being connected should have a parallel structure for consistency and readability.
Examples:
- ❌ “She enjoys hiking, biking, and to swim.”
- ✅ “She enjoys hiking, biking, and swimming.”
Practice Exercises
Use the following exercises to practice meaning, punctuation, and parallel structure:
1. Sentence Completion Challenge

2. FANBOYS Matching Game
- Materials: Create flashcards with coordinating conjunctions (e.g., “For,” “And,” “But”) and matching sentence fragments (e.g., “it was late,” “I was tired.”)
- Instructions: Students match the conjunctions cards with the correct sentence fragments to form logical sentences.
- Objective: Help learners identify the correct conjunction based on context.
3. Identify and Correct Errors
- Instructions: Provide sentences with incorrect usage of coordinating conjunctions and have students identify and correct the errors.
- Example:
Here are sentences containing errors involving coordinating conjunctions. Identify the mistake and rewrite the sentence correctly.
1. She wanted to go shopping, she didn’t have enough money.
2. He studied hard for the exam but he didn’t prepare for the essay question.
3. The cake was delicious but it was too sweet for my liking.
4. I don’t like horror movies, nor I enjoy comedies.
5. They wanted to go hiking it rained all weekend.
Answers:
1. Error: Comma splice.
Corrected: She wanted to go shopping, but she didn’t have enough money.
2. Error: Missing comma before conjunction connecting two independent clauses.
Corrected: He studied hard for the exam, but he didn’t prepare for the essay question.
3. Error: Missing comma before “but” connecting independent clauses.
Corrected: The cake was delicious, but it was too sweet for my liking.
4. Error: When “nor” introduces a second independent clause after a negative clause, the subject and auxiliary verb normally invert.
Corrected: I don’t like horror movies, nor do I enjoy comedies.
5. Error: Missing coordinating conjunction between two independent clauses.
Corrected: They wanted to go hiking, but it rained all weekend.

These activities can be adapted for different age groups and proficiency levels by adjusting the vocabulary, sentence length, and number of clauses.
Frequently Asked Questions
1. What is the difference between coordinating and subordinating conjunctions?
Coordinating conjunctions join words, phrases, or clauses of equal grammatical status. Subordinating conjunctions introduce a dependent clause and relate it to an independent clause.
- Coordinating: “I wanted to go swimming, but it started raining.”
- Subordinating: “Although I wanted to go swimming, it started raining.”
2. Do you always need a comma before a coordinating conjunction?
Use a comma before a coordinating conjunction when it joins two independent clauses. Do not add that comma when the conjunction joins only words, phrases, or verbs in a compound predicate, although other punctuation rules may still require commas in the sentence.
3. Are all conjunctions part of FANBOYS?
No. FANBOYS names the seven coordinating conjunctions commonly taught in English. Subordinating conjunctions such as because, although, and since, as well as correlative pairs such as either/or, neither/nor, and not only/but also, are not part of FANBOYS.
4. Can coordinating conjunctions connect more than two elements?
Yes. A coordinating conjunction can link the final two items in a series of three or more words, phrases, or clauses. Commas normally separate the preceding items, and the applicable style guide determines whether a serial comma appears before the final conjunction.
Example: “I bought apples, oranges, bananas, and grapes.”
Reflection
Understanding coordinating conjunctions helps writers connect parallel elements and independent clauses clearly. FANBOYS is a useful memory aid, but accurate use also depends on meaning, punctuation, and sentence structure.
Practice identifying what each conjunction joins, checking whether both sides are independent clauses, and revising errors involving commas, run-ons, or parallelism.
