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 verb.
