What is a run on sentence?
A run on sentence is one in which two or more sentences are joined together without punctuation or conjunction. Sentences are separate if they have different subjects and actions. For example; “my spelling is terrible the dissertation will be rejected” is a run on sentence; we are talking about me and my spelling then about my dissertation and it being rejected; two subjects and two actions with nothing to separate them. This could be corrected by placing a comma in the middle; “my spelling is terrible, the dissertation will be rejected” but that is a “comma splice’ and is considered by some to be wrong also.
A more correct form would be “my spelling is terrible therefore the dissertation will be rejected” or even “my spelling is terrible; the dissertation will be rejected.”
A run on sentence does not have to be a lengthy sentence; the one used above has only 9 words; in fact a sentence can be as long as you would like as long as you can join it in the correct form to keep it flowing; after all how long is this sentence and how many joins does it contain?
Preventing run on sentences
Now my word processor has seen each and every version that I have above and has highlighted none of them as being grammatically incorrect, however if my word processor was my old professor from when I did my degree it would have rapped my knuckles and told me to correct my work!
I need a run on sentence checker that is as efficient as my old professor rather than what this one can do, after all if I were writing a dissertation now I would hope that my grammar checker would highlight the problem so that I could correct it before I submitted my dissertation.
There are free run on sentence checkers available on the internet that you could use.
