How do you grammar check sentences for a sentence fragment and run-on errors?
Finding a solution is simple, once you can recognize what the problem is with a sentence. When you write in a hurry, you will always have a few corrections you will need to make.
It’s easy to make little grammar and spelling mistakes or use misused words. I don’t think there is a writer who doesn’t make a spelling error occasionally.
Every writer does a quick spell check and proofreads for simple grammar errors. But what about errors at a sentence level?
Grammar check at the sentence level
You have to pay careful attention when proofreading or grammar checking to how you structure both short or long sentences 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.
Of course, making sure that you join all the clauses correctly and in the right order is what good writing is all about.
The most common problems with sentence structure are 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?
The usual causes of a sentence fragment are that the sentence is lacking a subject or a verb.
Perhaps there is a separated prepositional phrase or dependent clause.
Look for the following errors to help you when you are revising the fragment.
Check for any fragments in your sentences and then correct them to make sure each sentence is complete.
Sentence fragment examples

Looking forward to meeting you on Saturday. Incorrect
I’m looking forward to meeting you on Saturday. Correct
He was scared. Running in fear towards the forest. Incorrect

There is no verb

It was Christmas and a time of merriment and joy. Correct
I found a great new job. The remedy for all my financial problems. Incorrect
I found a great new job, which will be the remedy for all my financial problems. Correct
Separated prepositional phrase
We had a great time. In spite of the rain. Incorrect

He lived in Rome. For many years. Incorrect

Dependent clause sentence fragment

John ran quickly to his office. To be sure he was on time. Incorrect
To be sure he was on time, John ran quickly to his office. Correct
2. What is a run-on sentence?
A run-on sentence is also called a fused sentence.
This mistake occurs when you join two independent clauses that are complete sentences together.
But they are not correctly connected. Clauses that you do not join accurately 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.
These include after, although, as, and because as a way to join two clauses and create a correct 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.
Run-on sentence examples

The next phase will be more difficult, so you should get ready as soon as you can. Correct

I can’t figure out how to set up this router because it came without an instruction manual. Correct

We’ll go to the cinema, and then we’re going to have dinner. Correct
We’ll go to the cinema. Then we’re going to have dinner. Correct
The taxi didn’t arrive, therefore, we had to walk home. Incorrect
The taxi didn’t arrive. Therefore, we had to walk home. Correct
We had to walk home because the taxi didn’t arrive. Correct
3. What is a compound sentence?
There are three types of sentences, 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 creates a compound-complex sentence.
Compound sentence examples

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
