Choose punctuation to avoid fragments and run-ons

Key Notes:

1. Understanding Sentence Fragments:

  • Definition: A sentence fragment is an incomplete sentence that lacks a subject, a verb, or a complete thought.
  • Example of a Fragment: After the rain stopped. (Missing the main clause)
  • How to Fix: Add the missing components to complete the thought.
    • Corrected Example: After the rain stopped, we went outside.

2. Identifying Run-On Sentences:

  • Definition: A run-on sentence occurs when two or more independent clauses are joined without proper punctuation or conjunctions.
  • Example of a Run-On: I love reading it helps me relax.
  • How to Fix:
    • Add a Period: Separate the clauses into two sentences.
      • I love reading. It helps me relax.
    • Use a Comma and a Coordinating Conjunction: Add a conjunction like and, but, or so.
      • I love reading, and it helps me relax.
    • Use a Semicolon: If the clauses are closely related, a semicolon can be used.
      • I love reading; it helps me relax.

3. Using Punctuation Correctly:

  • Periods (.)
    • Purpose: To end a complete thought or sentence.
    • When to Use: When separating independent clauses that aren’t closely related.
    • Example: The sun set. We went inside.
  • Commas (,):
    • Purpose: To join two independent clauses with a coordinating conjunction (and, but, so, or, for, nor, yet).
    • When to Use: To avoid a run-on sentence by connecting clauses with a conjunction.
    • Example: She wanted to go to the park, but it started to rain.
  • Semicolons (;):
    • Purpose: To join two closely related independent clauses without using a conjunction.
    • When to Use: When the clauses are closely related and could be separated by a period but are better kept together.
    • Example: The project was challenging; everyone worked extra hours to complete it.
  • Colons (:):
    • Purpose: To introduce a list, explanation, or elaboration of the previous clause.
    • When to Use: After a complete sentence that introduces the next part of the sentence.
    • Example: She brought everything she needed for the trip: clothes, toiletries, and snacks.

4. Avoiding Comma Splices:

  • Definition: A comma splice occurs when two independent clauses are joined with just a comma.
  • Example of a Comma Splice: She was tired, she went to bed.
  • How to Fix:
    • Use a Period: She was tired. She went to bed.
    • Add a Coordinating Conjunction: She was tired, so she went to bed.
    • Use a Semicolon: She was tired; she went to bed.

5. Combining Sentences Correctly:

  • Conjunctions: Use and, but, or, so to join ideas while making sure each clause is complete.
    • Example: The dog barked, and the cat hissed.
  • Subordinating Conjunctions: Use words like because, since, although, if to connect a dependent clause to an independent clause.
    • Example: Although it was raining, we went for a walk.
