Is This A Run On Sentence

The English language, with its intricate grammar rules, can sometimes feel like a minefield. One common stumbling block is the run-on sentence, a grammatical error that can make your writing confusing and difficult to read. Understanding what a run-on sentence is and how to identify and correct it is crucial for clear and effective communication. This comprehensive guide will break down everything you need to know about run-on sentences, helping you master the art of writing grammatically sound and engaging prose.

What Exactly is a Run-On Sentence?

A run-on sentence occurs when two or more independent clauses are joined together without proper punctuation or conjunctions. An independent clause is a group of words that can stand alone as a complete sentence because it contains a subject and a verb and expresses a complete thought. Think of it as a sentence trying to do too much at once, like cramming multiple ideas into a single breath.

Let's illustrate with an example:

Run-on: The rain was pouring down the streets were flooded.

In this example, we have two independent clauses:

• The rain was pouring down.
• The streets were flooded.

These are two separate thoughts that are simply mashed together without any connecting words or punctuation. This is what creates the run-on.

Types of Run-On Sentences: Fused and Comma Splices

Run-on sentences come in two main varieties: fused sentences and comma splices. While both involve connecting independent clauses improperly, they differ slightly in how they do so.

Fused Sentences: The Punctuation-less Offender

A fused sentence, also known as a run-together sentence, is the most straightforward type of run-on. It occurs when two or more independent clauses are joined together with no punctuation whatsoever. It's as if the sentence just runs on and on, hence the name.

Example: The sun shone brightly the birds sang sweetly.

Here, "The sun shone brightly" and "the birds sang sweetly" are both independent clauses that are incorrectly fused together without any punctuation.

Comma Splices: The Comma's Misguided Attempt

A comma splice occurs when two or more independent clauses are joined together only by a comma. While a comma is a form of punctuation, it's not strong enough on its own to correctly join independent clauses. It's like trying to hold two heavy objects together with a single piece of tape – it's likely to fail.

Example: I went to the store, I bought some milk.

In this case, "I went to the store" and "I bought some milk" are independent clauses incorrectly joined by a comma.

Why are Run-On Sentences Problematic?

Run-on sentences create several problems for your writing, ultimately hindering effective communication.

• Lack of Clarity: When independent clauses are strung together without proper separation, it becomes difficult for the reader to understand the relationship between the ideas. The reader has to work harder to parse the meaning, which can lead to confusion.
• Impaired Readability: Long, rambling sentences are simply harder to read. Readers are more likely to lose interest or become fatigued when faced with sentences that don't flow smoothly.
• Weakened Impact: Run-on sentences can diminish the impact of your writing. The individual ideas within the sentence lose their emphasis because they're buried within a jumble of words.
• Lack of Professionalism: Using run-on sentences can make your writing appear sloppy and unprofessional. It suggests a lack of attention to detail and a poor grasp of grammar.

Identifying Run-On Sentences: A Step-by-Step Guide

The first step in fixing run-on sentences is being able to identify them in your own writing. Here's a step-by-step approach:

1. Read the Sentence Carefully: Pay close attention to the sentence's structure and flow. Does it feel like it's trying to say too much in one breath?
2. Identify Potential Independent Clauses: Look for groups of words that could stand alone as complete sentences. Remember, an independent clause must contain a subject and a verb and express a complete thought.
3. Check for Connecting Punctuation or Conjunctions: Are the independent clauses joined by a comma alone (comma splice) or by no punctuation at all (fused sentence)?
4. If you find two or more independent clauses joined incorrectly, you've likely identified a run-on sentence.

Let's practice with a few examples:

• Example 1: The dog barked loudly, it chased the squirrel up the tree.
  • "The dog barked loudly" (independent clause)
  • "it chased the squirrel up the tree" (independent clause)
  • Joined by a comma alone = Comma Splice
• Example 2: She loves to read books they transport her to different worlds.
  • "She loves to read books" (independent clause)
  • "they transport her to different worlds" (independent clause)
  • Joined by no punctuation = Fused Sentence
• Example 3: The chef prepared a delicious meal, and the guests enjoyed every bite.
  • "The chef prepared a delicious meal" (independent clause)
  • "the guests enjoyed every bite" (independent clause)
  • Joined by a comma and a coordinating conjunction ("and") = Correct Sentence (not a run-on)

Methods for Correcting Run-On Sentences: The Grammar Toolkit

Once you've identified a run-on sentence, you have several options for correcting it. The best method will depend on the specific context and the relationship between the ideas being expressed. Here are the most common and effective techniques:

1. Separate into Two Sentences: This is often the simplest and most direct solution. Break the run-on sentence into two separate sentences, each with its own subject and verb.

   • Run-on: The movie was long, I almost fell asleep.
   • Corrected: The movie was long. I almost fell asleep.

   This method is best when the two independent clauses express distinct ideas that don't require a close connection.

2. Use a Comma and a Coordinating Conjunction: Coordinating conjunctions (such as and, but, or, nor, for, so, and yet) can be used to join two independent clauses that are closely related.

   • Run-on: She wanted to go to the beach, it was raining.
   • Corrected: She wanted to go to the beach, but it was raining.

   Using a comma before the coordinating conjunction is crucial. This method works well when the clauses have a clear relationship, such as contrast ("but"), addition ("and"), or cause and effect ("so").

3. Use a Semicolon: A semicolon (;) can be used to join two closely related independent clauses. It indicates a stronger connection between the clauses than a comma alone but not as strong as a period.

   • Run-on: The concert was amazing, the band played all their hits.
   • Corrected: The concert was amazing; the band played all their hits.

   Use a semicolon when the clauses are related and you want to emphasize the connection between them.

4. Use a Colon: A colon (:) can be used to introduce an explanation, example, or list that clarifies or expands upon the first independent clause.

   • Run-on: He had one goal in mind he wanted to win the race.
   • Corrected: He had one goal in mind: he wanted to win the race.

   The first clause should be a general statement, and the second clause should provide specific information about it.

5. Subordinate One of the Clauses: Subordination involves making one of the independent clauses into a dependent clause, which cannot stand alone as a sentence. This is done using subordinating conjunctions (such as because, although, since, while, if, when, after, before, unless, until, as) or relative pronouns (such as who, which, that).

   • Run-on: The game was over, we went home.
   • Corrected: Because the game was over, we went home. (Subordinating conjunction)
   • Corrected: We went home after the game was over. (Subordinating conjunction)

   Subordination is useful when one idea is less important than the other and provides context or explanation.

Advanced Techniques and Considerations

While the methods above cover the basics of correcting run-on sentences, here are some more advanced techniques and considerations to keep in mind:

• Vary Your Sentence Structure: Don't rely on the same correction method every time. Mix it up to keep your writing interesting and engaging.
• Consider the Flow: Choose the correction method that best enhances the flow of your writing. Sometimes breaking the sentence into two is the most effective way to improve readability, while other times, using a semicolon or subordinating conjunction creates a smoother transition.
• Pay Attention to Emphasis: Think about which ideas you want to emphasize. Breaking a sentence into two separate sentences gives each idea more prominence. Subordinating one clause emphasizes the other.
• Use Conjunctive Adverbs Sparingly: Conjunctive adverbs (such as however, therefore, moreover, furthermore, nevertheless) can be used with a semicolon to join independent clauses. However, overuse can make your writing sound stiff and formal.
  • Example: The project was challenging; however, we managed to complete it on time.
• Avoid Over-Correction: Not every long sentence is a run-on. Sometimes, a long sentence is grammatically correct and effective. The key is to ensure that it is punctuated properly and flows well.

Run-On Sentences vs. Long Sentences: Knowing the Difference

It's important to distinguish between run-on sentences and simply long sentences. A long sentence is not necessarily incorrect as long as it contains only one independent clause or multiple independent clauses that are correctly joined with appropriate punctuation and conjunctions. The problem arises when independent clauses are improperly joined, creating a run-on.

Example of a Long, Correct Sentence: Although the weather was unpredictable, and the journey was arduous, they persevered, because their determination was unwavering and their destination held the promise of a new beginning.

This sentence is long, but it is grammatically correct because the clauses are properly connected with coordinating and subordinating conjunctions.

Common Mistakes to Avoid

Here are some common mistakes to watch out for when dealing with run-on sentences:

• Using "and then" or "so then" to Join Clauses: While "and then" and "so then" can be used in sentences, they are not strong enough to join independent clauses without a comma before them.
  • Incorrect: She finished her work and then she went home.
  • Correct: She finished her work, and then she went home.
• Confusing Dependent and Independent Clauses: Make sure you can accurately identify independent and dependent clauses. A dependent clause cannot stand alone as a sentence.
• Overusing Commas: While commas are important, they are not a cure-all for grammatical problems. Don't rely solely on commas to join independent clauses.
• Ignoring the Relationship Between Ideas: Choose the correction method that best reflects the relationship between the ideas you are expressing.

Run-On Sentences in Different Writing Styles

The tolerance for long sentences and complex structures can vary depending on the writing style. For example:

• Academic Writing: Academic writing often requires complex sentences to express nuanced ideas, but it also demands strict adherence to grammatical rules. Run-on sentences are unacceptable.
• Journalistic Writing: Journalistic writing prioritizes clarity and conciseness. Shorter sentences are generally preferred, and run-on sentences should be avoided.
• Creative Writing: Creative writing allows for more flexibility and experimentation with sentence structure. However, even in creative writing, run-on sentences should be used intentionally and sparingly, only when they serve a specific artistic purpose.

Practicing and Improving Your Skills

The best way to master run-on sentences is to practice identifying and correcting them. Here are some exercises you can try:

1. Find Examples: Look for examples of run-on sentences in books, articles, or online content.
2. Practice Correction: Take run-on sentences and try correcting them using different methods.
3. Review Your Own Writing: Carefully review your own writing for run-on sentences.
4. Seek Feedback: Ask a friend, teacher, or colleague to review your writing and provide feedback on your sentence structure.

By consistently practicing and applying the techniques discussed in this guide, you can significantly improve your ability to identify and correct run-on sentences, resulting in clearer, more effective, and more professional writing.
