7. Sentence Fragments • A sentence fragment is a group of words looking likea complete sentence. Sentence fragments, as incomplete sentences, can confuse your reader or make your meaning unclear. There is an easy way to test for sentence completeness. Ask the following sentences as you are writing:

8. Sentence Fragments • Is there a verb (action word)? • Is there a subject? • If the phrase starts with a subordinating word (like "because" or "since"), does it also include an independent clause to complete the thought? • If you answered "no" to any of these questions, you've got yourself a sentence fragment.

9. Correct sentence fragments • Expand the fragments into sentences, supplying the missing elements like subjects, verbs, and clauses.  Incorrect: Confusing and distracting to readers.  Correct: Sentence fragments are confusing and distracting to readers.  Incorrect: Because they are confusing and distracting to readers.  Correct: Because they are confusing and distracting to readers, writers should generally avoid sentence fragments.

12. Correct sentence fragments • Add a subject to the fragment. Incorrect: Wanted to get to work on time. Correct: Frank wanted to get to work on time.

13. Non-parallel sentences • Parallel sentence structure is about balancing your sentences. The words "and," "but" and "or" are conjunctions, used to join ideas and comparisons in sentences. The ideas and comparisons on each side of these words should be balanced out in order to be considered parallel. If they are not balanced out then they are nonparallel sentences.

14. Correct Non-parallel sentences • Use the same form of comparison words within a sentence. Incorrect: He likes playing and to run at recess. Correct: He likes playing and running at recess. Incorrect: Her details of the events were recounted correct and clearly. Correct: Her details of the events were recounted correctly and clearly

16. Correct Non-parallel sentences • Make sure the verb usage is balanced out. If you use a verb with one word, use a verb with all of the words on each side of your "and," "but" and "or.“ Incorrect: Newborns frequently cry and are restless at night. Correct: Newborns frequently cry and restless at night.

17. Correct Non-parallel sentences • Place your connecting words so that they come before both of the ideas that you are connecting. Incorrect: She was not only the best person on our team, but a good friend too. Correct: She not only was the best person on our team, but a good friend too.

18. Run-on sentence • A run-on sentence is a sentence in which several main clauses are strung together without proper punctuation and so run together as if they were one sentence. Run-on sentences make your reader's job difficult; they interrupt the rhythm of your writing and condense too much information into a small space. 

19. Correct Run-on sentences • Separate the independent clauses into two sentences.  Incorrect: They gossiped about many things at lunchthey always have the most to say about their coworkers. Correct: They gossiped about many things at lunch. They always have the most to say about their coworkers.

20. Correct Run-on sentences • If the ideas expressed in the clauses are connected, they can be joined with a semi-colon. Incorrect: They gossiped about many things at lunchthey always have the most to say about their coworkers. Correct: They gossiped about many things at lunch; they always have the most to say about their coworkers.

21. Correct Run-on sentences • Subordinate one of the clauses. That is, first employ a word or phrase as a subordinator like although, while, because, and whereas. Then, add commas where needed, and go from there.  Incorrect: They gossiped about many things at lunchthey always have the most to say about their coworkers. Correct: Although they gossiped about many things at lunch, they always have the most to say about their coworkers.
