Pezdek's Top Ten List of Writing Issues
C
Clarify
The point that you are trying to make here needs to be developed and clarified better. I do not know what you are trying to say here.
Cas
Casual
Your writing style here is too casual; this does not read like professional writing.
K
Awkward
Read this sentence out loud and think of a better way to say this that is less awkward.
N
Unnecessary
Think about the organizational structure of your paper and whether this material is necessary for the specific point you are making here.
Red
Redundant
You have already made this point. Check the organizational structure of your paper and decide where the best place is to make this pint.
Ref
Referent
It is not clear what the referent for this word is.
S
Structure
The structure of your paper is not clear at this point. I cannot tell where you are going. Develop a clear structure to your paper and make it explicit in the paper as you move through this structure.
T
Transition
The transition here is not clear. Think about what you just said, the point you want to make next, and then use clear language to articulate the transition between these ideas.
U
Unpack
Unpack the relevant references more systematically. For each major point, decide what the most relevant reference is and focus on presenting this work. Then present related but secondary references more succinctly.
W
Wordy
Think of a more succinct way to say this.
