What is a Fused Sentence? Definition and Examples for AP Lang

📚 Quick Study Guide: Fused Sentences

• 💡 What is a Fused Sentence? A fused sentence (also known as a run-on sentence) occurs when two or more independent clauses are joined together without any punctuation or a coordinating conjunction. It's essentially two complete thoughts "smashed" together.
• ⚠️ The Problem: Fused sentences make writing confusing, difficult to read, and grammatically incorrect. They obscure the relationship between ideas.
• ✂️ How to Fix Fused Sentences:
  • ✏️ 1. Use a Period: Separate the two independent clauses into two distinct sentences.
    Example: The dog barked loudly. The cat hissed back.
  • ➕ 2. Use a Comma and a Coordinating Conjunction (FANBOYS): Join the clauses with a comma followed by one of the FANBOYS (For, And, Nor, But, Or, Yet, So).
    Example: The dog barked loudly, and the cat hissed back.
  • 🔗 3. Use a Semicolon: Connect two closely related independent clauses.
    Example: The dog barked loudly; the cat hissed back.
  • ➡️ 4. Use a Semicolon with a Conjunctive Adverb: Use a semicolon, a conjunctive adverb (e.g., however, therefore, moreover, consequently), and a comma.
    Example: The dog barked loudly; however, the cat hissed back.
  • 📝 5. Subordination: Make one of the independent clauses dependent by adding a subordinating conjunction (e.g., because, although, while, since).
    Example: Because the dog barked loudly, the cat hissed back.
• 🎓 AP Lang Relevance: Mastering fused sentences is crucial for AP Language and Composition. Clear, grammatically correct sentences demonstrate sophisticated control over language, which is highly valued in essays and rhetorical analysis.
