Coordinating Conjunctions Guide: FANBOYS Explained with Examples, Mistakes & Quiz
A coordinating conjunction is a short connector—like for, and, nor, but, or, yet, so—that links words, phrases, or clauses of equal grammatical rank. Use them to balance ideas smoothly and to join two independent clauses without creating run-ons or fragments.
Even native U.S. English speakers trip over coordinating conjunctions—those short words that balance sentences but hide punctuation traps. This guide covers the seven FANBOYS with precise uses, U.S. comma rules, tricky look-alikes (so, for, yet), common mistakes, an interactive quiz, and FAQs.
What Are Coordinating Conjunctions? (Definition & Role)
A coordinating conjunction connects words, phrases, or clauses of equal importance. In professional U.S. prose, they help you build balanced, readable sentences without run-ons or fragments. The headline rule: coordinating joins equals; subordinating creates dependence.

The 7 Coordinating Conjunctions (FANBOYS List)
Remember FANBOYS: For, And, Nor, But, Or, Yet, So. Functions + examples:
- For → reason (formal): “I stayed home, for it was raining.”
- And → addition: “She sings and dances.”
- Nor → negative alternative: “He neither called nor texted.”
- But → contrast: “It’s expensive, but worth it.”
- Or → choice: “Tea or coffee?”
- Yet → contrast (slightly more formal than but): “He’s tired, yet determined.”
- So → result: “It rained, so we canceled.”
10 Examples of Coordinating Conjunctions in Sentences

U.S. Punctuation with FANBOYS (Comma Rules That Matter)
- Comma before FANBOYS when joining two independent clauses.“She finished the report, and she sent it.”
- No comma if you’re just joining words/short phrases. “She finished the report and sent it.”
- Don’t use FANBOYS to join unequal parts. Use a subordinator instead. “She left because it was late.” (Not “She left, so late.”)
- Oxford comma is a style choice—be consistent across a document.
Tricky Parts (Look-alikes & Edge Cases)
- For (conjunction of reason) vs. for (preposition): “We paused, for the road was flooded.” vs. “This is for you.”
- So (result conjunction) vs. degree adverb: “It was late, so we left” vs. “So late!”
- Yet (contrast conjunction) vs. temporal adverb: “It’s risky, yet doable” vs. “We haven’t started yet.”
- Nor after negatives + inversion in formal style: “I didn’t call; nor did I text.”
Common Mistakes (and Quick Fixes)
Mistake | Bad Example | Fix |
---|---|---|
Comma splice / run-on | I ran, I fell. | Add FANBOYS: I ran, and I fell. |
Missing comma before FANBOYS (two clauses) | She ate and she slept. | She ate, and she slept. |
Joining unequal parts | Run but carefully. | Use a subordinator or rephrase: “Run carefully,” or “Run, but keep your pace steady.” |
Overstuffed lists | Apples and oranges and bananas… | Use commas + one conjunction; be consistent with Oxford comma. |
Coordinating vs. Subordinating Conjunctions (The Clean Contrast)
Coordinating (FANBOYS) join equals—often two independent clauses: “I was tired, so I left.” Subordinating (because, although, if) create dependence: “I left because I was tired.”
Commas: In U.S. English, put a comma before FANBOYS when they join independent clauses. Subordinating conjunctions don’t usually need one unless the dependent clause comes first: “Because I was tired, I left.”
