This lesson explains the concepts of run-on sentences and comma splices, which occur when two independent clauses are improperly joined. A run-on sentence lacks any punctuation or connecting words, while a comma splice incorrectly uses a comma to connect two complete thoughts. To correct these errors, writers can use a semicolon or add a conjunction with a comma, enhancing the clarity and effectiveness of their writing.

Understanding Run-On Sentences and Comma Splices

In grammar, run-on sentences and comma splices are common mistakes that can make writing confusing. This article will help you understand what they are and how to fix them.

What is a Run-On Sentence?

A run-on sentence happens when two complete sentences (called independent clauses) are joined together without the right punctuation or words like “and,” “but,” or “or” to connect them properly.

Example of a Run-On Sentence

Take a look at this example:

“We bought nails we bought a hammer.”

In this sentence, there are two complete thoughts:

  1. We bought nails.
  2. We bought a hammer.

Since there’s no punctuation or connecting word, it’s a run-on sentence.

How to Fix a Run-On Sentence

Here are some ways to fix a run-on sentence:

  1. Using a Semicolon: You can use a semicolon to separate the clauses:
    “We bought nails; we bought a hammer.”
  2. Using a Comma with a Conjunction: You can also add a comma and a connecting word:
    “We bought nails, and we bought a hammer.”

What is a Comma Splice?

A comma splice is a type of run-on sentence where two complete sentences are joined by just a comma, which is not enough.

Example of a Comma Splice

For example:

“I love Li’l Tony 2: Pony Up 2 the Streets, it’s my favorite movie in the Li’l Tony franchise.”

Here, both parts can stand alone as sentences:

  1. I love Li’l Tony 2: Pony Up 2 the Streets.
  2. It’s my favorite movie in the Li’l Tony franchise.

But they are incorrectly joined by just a comma.

How to Fix a Comma Splice

To fix a comma splice, you can:

  1. Use a Semicolon: Replace the comma with a semicolon:
    “I love Li’l Tony 2: Pony Up 2 the Streets; it’s my favorite movie in the Li’l Tony franchise.”
  2. Use a Comma with a Conjunction: Add a connecting word:
    “I love Li’l Tony 2: Pony Up 2 the Streets, and it’s my favorite movie in the Li’l Tony franchise.”

Summary

In summary, run-on sentences and comma splices both involve joining complete sentences incorrectly. A run-on sentence has no punctuation or connecting word, while a comma splice uses a comma incorrectly. To fix these, you can use a semicolon or a comma with a conjunction. Understanding these concepts will help make your writing clearer and more effective!
