📚 Understanding FANBOYS and Commas
FANBOYS is a handy acronym to remember the coordinating conjunctions: For, And, Nor, But, Or, Yet, So. These words connect two independent clauses in a compound sentence. The rule is simple: use a comma before the FANBOYS conjunction when it joins two independent clauses.

📜 A Brief History
The use of commas has evolved over centuries. Originally, commas indicated a pause in speech. Over time, grammarians standardized their use to clarify sentence structure. The comma before FANBOYS is a key element in ensuring clarity and preventing misreading of compound sentences.

✨ The Key Principles

🔑 Independent Clauses: An independent clause contains a subject and a verb and can stand alone as a sentence.
  🤝 Coordinating Conjunctions (FANBOYS): These words link independent clauses.
  ✍️ The Comma's Role: The comma signals the separation of the two independent clauses, making the sentence easier to read and understand.

✔️ Correct and Incorrect Examples
Let's break down some examples to illustrate the correct and incorrect usage of commas with FANBOYS:

💡 Quick Tips
