Corrections

Be sure to use specific examples
 
Grammar, punctuation, usage -- all of these can affect coherence
EXAMPLES of abbreviations used in papers:

R-O = run-on sentence
CS = comma splice
TS  = tense shift
VPR = vague pronoun or vague pronoun reference
AGR = there is an agreement flaw
sp = spelling error

Composition abbreviations:
TR = transition is needed

Two terms to know:

• DICTION - refers to the words chosen--the key is to select the very best possible word for your sentence

Examples--for collegiate writing, you need to think more deeply, be more aware of words, and choose Better Words.  BW = better word
AVOID using the following:
a lot
great or nice
good
use words that are more formal, more academic
Don't confuse your words:
wonder / wander
then / than
death / deaf

• SYNTAX - the arrangement of words in a sentence or paragraph

Example of incorrect syntax:
"They did a commercial about a goat that is being sold by his owner who had an unusual craving for Doritos."

"They" ???  who are "they'?
Revised:

The advertising department for Doritos created
a commercial about a goat who had an unusual craving for Doritos  that was being sold by its owner.

Sentence that needs revision:
You think that when you get on Facebook that you're getting on just to check your notifications and you end up being on there for hours.

One way to revise: change 2nd person "YOU" to first person "I":

I think that when I get on Facebook that I'm getting on just to check my notifications, and I end up being on there for hours.

OR . . . change it to THIRD person: he/she/one/a person

A person may get on on Facebook, thinking he  will just check his notifications and end up being on there for hours.
