- Contains two independent clauses joined by a coordinating conjunction: for, and, nor, but, or, yet, and so (FANBOYS).
- A comma comes before the conjunction in a compound sentence.
- The coordinating conjunction shows the relationship between the two halves (independent clause) of the sentence.
| Conjunction | Purpose | |
| F | for | Shows a reason (the second clause gives a reason for the first) |
| A | and | Shows addition |
| N | nor | Shows a negative alternative (It’s the negative form of or, and it must follow a clause containing a negative word such as not. When we use nor we must use question word order after it. |
