Is it a complete sentence or a run-on?

Key Notes:

📝 Is it a Complete Sentence or a Run-On?

A complete sentence tells a complete thought. It has:

  • A subject 👦👧 (who or what the sentence is about)
  • A predicate 🏃‍♂️ (what the subject does or is)
  • Starts with a capital letter 🅰️
  • Ends with a punctuation mark (. ! ?)

Example:

  • 🌸 The flowers are blooming.
  • 🐶 The dog is barking loudly!

A run-on sentence happens when two or more complete sentences are joined without proper punctuation or connecting words.

Example:

  • Wrong: I like pizza I eat it every Friday.
  • Correct: I like pizza. I eat it every Friday.
  • Correct with a conjunction: I like pizza, and I eat it every Friday.
  • Look for two subjects and two verbs in one sentence without proper punctuation.
  • Check if it makes sense as one thought. If not → likely a run-on.
  • Use periods (.), semicolons (;), or conjunctions (and, but, or) to fix it.

Method 1: Add a period

  • Wrong: I love ice cream it is my favorite dessert.
  • Fixed: I love ice cream. It is my favorite dessert.

Method 2: Add a semicolon

  • Fixed: I love ice cream; it is my favorite dessert.

Method 3: Add a conjunction

  • Fixed: I love ice cream, and it is my favorite dessert.

Ask yourself:

Does it have one complete thought? 💡

No → ❌ Run-on

Yes → ✅ Complete sentence
