FANBOYS: The Seven Coordinating Conjunctions
Remember the main coordinating conjunctions using the acronym FANBOYS. Each letter stands for one word: For, And, Nor, But, Or, Yet, So. These conjunctions are commonly tested in school grammar exams. Practicing their usage helps in competitive tests and confident writing.
Coordinating Conjunctions vs. Subordinating Conjunctions
The main difference is that coordinating conjunctions connect parts of equal grammatical value, while subordinating conjunctions link a dependent idea to a main clause. For instance, "I studied but I was tired" uses a coordinating conjunction. In contrast, "Although I was tired, I studied" uses a subordinating conjunction.
- Coordinating: Connect equals ("She reads and writes.")
- Subordinating: Connects dependent with main ("Because it rained, we cancelled the game.")
Rules and Punctuation with Coordinating Conjunctions
When joining two independent clauses, use a comma before the coordinating conjunction. Example: "She wanted to go, but it was too late." If connecting single words or phrases, a comma is usually not needed.
- Right: I like books, and I enjoy music.
- Wrong: I like books and, I enjoy music.
Common Student Mistakes and Quick Tips
