<p>I have identified:
pronoun disagreement; singular-plural disagreement; idiomatic errors; comparison errors; parallelism; redundancy; misplaced modifier; pronoun ambiguity; diction errors; adjective-adverb misuse; verb tense errors; sentence fragments and run-ons; transition and punctuation errors; logic errors. Can anyone add more to the list I have so far?</p>
<p>passive voice</p>
<p>Pretty sure they’re all listed in silverturtle’s guide. It’s the most complete set I’ve seen - online or otherwise.</p>
<p>The use of the passive voice isn’t technically an error, though it is seldom found in a correct anwer because it is inefficient most of the time.</p>
