What is a run-on sentence and how to fix it?

“The commas are the signposts leading the reader through the labyrinth of your sentence. Omit one, and your reader is likely to get lost.”Unknown

Run-on sentences are like the marathoners of the grammatical world. They just keep running, and running, and running. They are long-winded, exhausting, and often confusing. But what exactly is a run-on sentence and how can we go about fixing it? Let’s break it down.

Understanding Run-on Sentences

A run-on sentence occurs when two or more independent clauses (complete sentences) are connected improperly. It’s not about the length of the sentence, but rather about the punctuation and linkage of ideas. Grammarly provides a succinct definition of a run-on sentence.

Consider the following example:

“I love reading books I spend hours every day doing it.”

At first glance, this might just seem like a long sentence, but it’s actually a run-on. Why? Because there are two complete thoughts, each with its subject and predicate: “I love reading books” and “I spend hours every day doing it”. They are ‘running on’ into each other without proper punctuation or conjunctions.

How to Spot and Fix Run-on Sentences (grammar)

Now that we understand what a run-on sentence is, let’s explore how to spot and correct them. This will not only make your writing more precise and easier to read but also increase its Google readability score, an essential factor in SEO ranking.

1. Use a Period

The simplest way to fix a run-on sentence is by breaking it into two separate sentences using a period.

Example:

“I love reading books. I spend hours every day doing it.”

2. Use a Comma and a Coordinating Conjunction

If the two independent clauses are closely related, you might prefer to keep them together. In this case, use a comma followed by a coordinating conjunction (and, but, for, nor, yet, or, so).

Example:

“I love reading books, and I spend hours every day doing it.”

3. Use a Semicolon

If the two independent clauses are closely related and you want to avoid using a coordinating conjunction, you can use a semicolon. It acts as a sort of ‘soft period’ that shows a close relationship between the clauses.

Example:

“I love reading books; I spend hours every day doing it.”

It’s important to remember that not all long sentences are run-on sentences. Long sentences can be perfectly grammatical if they are structured correctly. The issue with run-on sentences is that they can make your writing hard to follow. By learning to identify and correct run-on sentences, you can make your writing clearer and more effective.

Run-on Sentences: The Bottom Line

Grammar may seem like a small detail, but it’s the foundation of effective communication. By mastering concepts like run-on sentences, you can enhance your writing, improve readability, and ultimately, connect better with your readers.

  3. Using a semicolon:
    > “I’m a fan of sci-fi novels; they transport me to other worlds.”
