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

Complete Sentence ✅

A complete sentence expresses a complete thought.

  • Has a subject (who/what) 🌿
  • Has a predicate (what the subject does or is) ⚡
  • Starts with a capital letter and ends with . / ? / !

Examples:

  1. 🌞 The sun rises in the east.
  2. 🐶 The dog barked loudly.
  3. 🎂 My sister is baking a cake.
Fragment ❌

A fragment is not a complete sentence.

  • Missing a subject, a predicate, or a complete thought
  • Often cannot stand alone

Examples:

  1. 🌧️ Because it was raining.
  2. 🍎 Eating a juicy apple.
  3. 🚗 When we reached the station.
Run-On Sentence ⚡

A run-on sentence is two or more complete sentences joined incorrectly

  • Missing punctuation or conjunctions
  • Often too long or confusing

Examples:

  1. 🌳 I went to the park I saw my friend. ⚡ (Needs a period or “and”)
  2. 🐦 The birds are singing the sun is shining.
  3. 🎒 She packed her bag she forgot her lunch.
