Fix A Sentence Fragment

It is easy to correct a sentence fragment or a run on sentence

Finding a solution is simple, once you can recognise what the problem is with a sentence.

When you write in a hurry, there will always be corrections that you will need to make.

One area you should pay careful attention to when proofreading or grammar checking is how you structure a short or a long sentence in your text.

In a well-formed sentence, you express a complete thought that should make perfect sense to your reader. The basic rule of a complete sentence is that it is a group of words that contains a subject and a verb.

Simple sentences usually have a subject and a verb plus an object. For example, I walk my dog.

In complex sentences or compound sentences, you can use many more devices.

These include defining and non-defining clauses, coordinating conjunctions, dependent clauses, independent clauses and punctuation such as commas or even semicolons.

Of course, making sure that all the clauses are joined correctly and in the right order is what good writing is all about.

The most common problems with sentence structure are fragmented sentences, run on sentences, comma splices and fused sentences.

Take a look at the following examples to help you understand how these sentence structures work.

 

1. What is a sentence fragment?

sentence fragment

The usual causes of this error are that the sentence is lacking a subject or verb or there is a separated prepositional phrase or dependent clause.

Look for the following errors when you are revising the fragment. Check for any fragments in your sentences and then correct them to make sure each sentence is complete.

2. What is a run on sentence?

Run On Sentence

A run on sentence is also called a fused sentence.

This mistake occurs when two independent clauses, which are in fact complete sentences, are joined together without being correctly connected. Clauses that are not connected correctly can create confusion for a reader.

Conjunctions like and, but, for, nor, yet, or, so can often fix the problem.

You can also use a subordinating conjunction such as after, although, as and because as another way to join two clauses correctly and create a second subordinating clause.

Adding a conjunctive adverb such as however, moreover, therefore or nevertheless can also be used as a solution.

Another form of a run on sentence is called a comma splice. It happens when a comma joins two independent clauses. The solution to this problem is usually to separate them into two sentences and add a capital letter.

3. What is a compound sentence?

compound sentence

There are three types, which are compound, complex and compound-complex.

A compound sentence consists of at least two independent clauses.

However, a complex sentence consists of an independent clause and at least one additional dependent clause.

Joining independent clauses together using these two forms together creates a compound-complex sentence.

 

Compound sentence examples

I ran out of money, so I had to cut short my vacation.

I wanted to go to work, but I was just too sick.

She hasn’t been to New York, nor has she been to Los Angeles.

Judy hates going to the dentist, but she went for her check up on Monday.

He got home at seven and then he went straight to bed.

 

Complex sentence examples

Apple has posted huge profits since it released the iPhone.

Although Mary was nervous, she passed her driving test.

Because I was running late, I grabbed a sandwich to eat on the way.

Although it was fun, I was really tired when it finished.

I’ll keep this old phone in case I need it one day.

 

Compound-complex examples

Even if Tom like skiing, he doesn’t go very often because it is too expensive.

Mike forgot to buy a birthday present for his wife, so he gave her a gift card, which she spent very quickly.

I was saddened to learn that my friend’s mother, who was only fifty-three, had passed away after a long illness.

I grew up in Wellington, which is often called the Windy City, but moved to Sydney when I was thirty-five to start a new job.

 

Conclusion

When you want to write with clarity, keeping your sentences short and simple is the easiest way to do so. It is a formula that is used a lot in article and blog writing.

When you write with basic verb-subject-object sentences and avoid using the passive voice, your writing will be very easy to read. It is a style that suits online reading of blogs and articles.

However, in fiction, painting a scene requires longer and much more complex sentence structures, which need proper punctuation. By doing so though, the chances of making a few errors increases.

If you are unsure, using a good grammar checker like Grammarly or for authors, Prowritingaid can help you spot problems in your sentence structures and then you can repair them quite easily.

The examples I have listed in this article should help you recognise the different basic sentence types and help you correct them.

Understanding the differences between these basic structures will help you write better and more accurately.
