3. Correcting the Run-on There are 3 ways to correct a run-on sentence.
1. Divide the main clauses into separate sentences, using periods and capital letters.
2. Add a semicolon between the main clauses.
3. Use a comma and a coordinating conjunction between them.

5. Sentence Fragments
A group of words that is punctuated like a sentence but lacks a subject, verb, or both and fails to express a complete thought. For example:
Intrepid mountain climbers scaling a tall peak. Climb higher and higher. Up frozen slopes. When they reach the top.

6. Correcting a Fragment
Add the necessary subject, verb, or both to complete the thought.
Sometimes you can do this by combining the fragment with a nearby sentence or another fragment

8. Stringy Sentences
Contains too many ideas connected by words like and, so, then, and so, or, and then. Stringy sentences are repetitious and hard to follow because the relationships between ideas are unclear.

9. Example of Stringy Sentence
Mount Everest is in Asia’s Himalaya mountain range, and it is the world’s tallest mountain, and so climbing it was a great challenge, and Edmund Hillary and Tenzing Norgay first climbed it in 1953, and then all the world celebrated their triumph.

10. Correcting Stringy Sentences
Decide which ideas are closely related and which are not.
When they are not, place them in separate sentences.
When they are, combine them into one sentence by adding a subordinating conjunction that clarifies their relationship.

11. Corrected Sentence
Mount Everest is in Asia’s Himalaya mountain range. Because it is the world’s tallest mountain, Mt. Everest was a great challenge. When Edmund Hillary and Tenzing Norgay first climbed it in 1953, all the world celebrated their triumph.

12. Unnecessary shifts
An unnecessary change in verb tense or in the person, number, or gender of pronouns often confuses and distracts readers. For example:
According to local legends, a mysterious creature dwells in the Himalayas. Its local name is Yeti; some call it the Abominable Snowman. Judging from his footprints, he was a creature of monstrous size.
