Is it a complete sentence, a fragment, or a run-on?

  • A complete sentence has two important parts:
    • Subject: Tells who or what the sentence is about.
    • Predicate: Tells what the subject is doing or describes the subject.
  • It expresses a complete thought and makes sense on its own.
  • Example: “The dog barked.”
    • This is a complete sentence because it tells who (the dog) and what the dog did (barked).

  • A fragment is not a complete sentence. It is missing a subject, a predicate, or doesn’t express a complete thought.
  • Fragments can be parts of a sentence but don’t stand on their own.
  • Example: “Running down the street.”
    • This is a fragment because it doesn’t tell who is running or what happened.

  • A run-on sentence happens when two or more complete sentences are joined together without proper punctuation or connecting words.
  • Run-on sentences don’t have clear breaks and can be confusing to read.
  • Example: “The dog barked it ran down the street.”
    • This is a run-on sentence because it’s actually two sentences: “The dog barked.” and “It ran down the street.” They need punctuation or connecting words.

  • Step 1: Does it have a subject (who or what the sentence is about)?
  • Step 2: Does it have a predicate (what the subject does or is)?
  • Step 3: Does it make sense on its own and express a complete thought?
  • If yes, it’s a complete sentence.
  • Example: “The cat chased the mouse.”

  • Step 1: Does it lack a subject or a predicate?
  • Step 2: Does it fail to express a complete thought?
  • If it’s missing a part or doesn’t make sense alone, it’s a fragment.
  • Example: “Because it was raining.”
    • This is a fragment because it doesn’t tell what happened because of the rain.

  • Step 1: Look for two or more complete thoughts that are joined without punctuation or connecting words.
  • Step 2: Check if there are missing periods, commas, or conjunctions (like and, but, so).
  • If the sentence keeps going without a proper break, it’s a run-on.
  • Example: “I went to the park I played on the swings.”
    • This is a run-on because it’s two sentences put together without a period or conjunction.

  • Add the missing part (subject, predicate, or complete thought).
  • Example: Fragment: “Because it was raining.”
    • Fix: “We stayed inside because it was raining.”

  • Use a period to separate the sentences.
    • Example: “I went to the park. I played on the swings.”
  • Use a comma and conjunction to connect the sentences.
    • Example: “I went to the park, and I played on the swings.”

  • Complete Sentence: “The bird sang in the tree.”
  • Fragment: “In the tree.”
  • Run-On: “The bird sang in the tree it flew away.”

  • Example 1: “My sister plays soccer.”
    • This is a complete sentence.
  • Example 2: “Jumped over the fence.”
    • This is a fragment.
  • Example 3: “I love ice cream my brother likes cake.”
    • This is a run-on.
