1. Grammar: Sentence Structure
1.) Sentence Fragments
2.) Run on sentences

2. Sentence Fragments
Have you ever seen the term “frag” or “fragment” written on an essay you received back from a teacher?
Did you understand what the grammar problem was with that sentence or how to fix it?
A sentence fragment is an incomplete sentence.

3. Sentence Fragments A sentence fragment is an incomplete sentence.
To fix a sentence fragment you must make sure that the sentence has both a SUBJECT and a VERB.

4. Sentence Fragments Most sentence fragments lack a verb.
In this case add a verb to show the action that the subject is carrying out.
Other sentence fragments lack a subject (a person or thing carrying out the action, or verb)
If this is the case and the subject is not an “implied subject,” then you must add a subject to your sentence.

5. SUBJECT + VERB = Complete Sentence
Sentence Fragments
SUBJECT + VERB = Complete Sentence
The dog ate my homework! = Complete Sentence
Ate my homework! = Incomplete Sentence/ Fragment
The dog my homework!= Incomplete Sentence/ Fragment

11. Run-On Sentences
A run-on sentence occurs when two or more independent clauses are not joined correctly.
An independent clause is a group of words that can stand alone as a sentence, as in, The dog runs.
Your writing may be confusing or unclear if independent clauses are joined incorrectly. There are two types of run-on sentences: fused sentences and comma splices.

12. Run-On Sentences There are two types of run-on sentences:
fused sentences
and
comma splices

13. Run-On Sentences
A fused sentence occurs when independent clauses run together with no marks of punctuation or coordinating conjunctions to separate them.
EXAMPLE:
“My professor read my paper she said it was excellent.”
Independent clause Independent clause

14. Run-On Sentences
A comma splice occurs when two or more independent clauses are joined only by a comma.
EXAMPLE:
“My cat meowed angrily, I knew she wanted food.”
Independent Clause Independent clause

15. Solutions to Run-On Sentences
REVISE RUN-ON SENTENCES in one of four ways:
Use a comma and a coordinating conjunction (for, and, nor, but, or, yet, so).
Run-on: My professor read my paper she said it was excellent.
Correction: My professor read my paper, and she said it was excellent.

2. Use a semicolon (or, in some cases, a colon or a dash). You can use a semicolon alone or with a transitional expression (e.g., however, at any rate, in contrast, as a result, etc.). Run-on: My cat meowed angrily, I knew she wanted food. Correction: My cat meowed angrily; I knew she wanted food. Correction with a transitional expression: My cat meowed angrily; therefore, I knew she wanted food.

3. Separate the independent clauses into sentences. This is an especially good technique when one of the independent clauses is very long. Run-on: It seemed to Wanda that her daughter had more than enough crayons, they were strewn across the bedroom floor and some of them were broken, and, worse still, someone had used the stub of a red crayon to mark a sinister smiley face on the wall. Correction: It seemed to Wanda that her daughter had more than enough crayons. They were strewn across the bedroom floor, and some of them were broken. Worse still, someone had use

4. Restructure the sentence by subordinating one of the clauses.
You can subordinate a clause if one of the independent clauses seems less important than the other.
Note that a subordinated clause is no longer independent—it cannot stand on its own as a sentence.
Run-on: The largest tree by volume in the world is the General Sherman Sequoia, it is a little over 52,500 cubic feet.
Correction: The largest tree by volume in the world is the General Sherman Sequoia, which is a little over 52,500 cubic feet.
