What is a Compound Sentence? Definition and Strategic Use in AP Lang

📚 What is a Compound Sentence?

A compound sentence combines two or more independent clauses (complete sentences) into a single sentence. These clauses are usually joined by a coordinating conjunction (like 'and', 'but', 'or', 'nor', 'for', 'so', 'yet'), a semicolon, or a conjunctive adverb (like 'however', 'therefore', 'moreover'). Mastering compound sentences can add sophistication and nuance to your writing, especially in AP Language where sentence variety is key.

📜 A Brief History

The concept of combining sentences has existed since the early days of written language. As language evolved, the methods for connecting these clauses became more formalized, leading to the modern understanding of compound sentences. The formal grammar rules we know today developed over centuries.

🔑 Key Principles

• 🔍 Independent Clauses: Each part of the sentence must be able to stand alone as a complete thought.
• 🤝 Coordinating Conjunctions: Use FANBOYS (For, And, Nor, But, Or, Yet, So) with a comma to connect clauses. Example: She studied hard, so she aced the test.
• ; Semicolons: Join closely related independent clauses without a conjunction. Example: The rain fell heavily; the streets were flooded.
• ➕ Conjunctive Adverbs: Use adverbs like 'however', 'therefore', 'moreover' with a semicolon and comma. Example: He was tired; however, he kept working.

✍️ Real-World Examples

Here are some examples of compound sentences, demonstrating different methods of connection:

• 🍎 With 'and': The student completed her homework, and she submitted it on time.
• 🤔 With 'but': He wanted to go to the party, but he had to study for his exam.
• ✅ With 'so': She practiced every day, so she improved her skills.
• ; With a Semicolon: The sun shone brightly; the birds sang sweetly.
• 💡With 'however': The test was difficult; however, many students passed.
