Final answer:
Writers editing sentences for grammar and (a) usage errors will correct double negatives, properly place quotation marks, remove extraneous commas, and fix spelling mistakes. They also refine sentence structure, ensure consistency, and streamline language for clarity and conciseness.
Step-by-step explanation:
When writers are editing sentences for errors in grammar and usage, they are likely to do several things, including looking for errors in double negatives, adding missing quotation marks, deleting unnecessary commas, and looking for spelling errors to correct them. During this process, identifying and correcting errors involving mixed sentence structures, evaluating an essay for clarity, coherence, and language are critical steps. Beyond these, writers should also check for subject/verb agreement errors, avoid comma splices, use proper capitalization, minimize the use of passive voice, and ensure verb tense consistency.
Proofreading is another key aspect of editing, in which the focus is on smaller details like typos and formatting according to style guides like MLA or APA. Adjusting for clarity often involves refining descriptions and, in the case of quotations, ensuring that they are grammatically compatible with the surrounding text. Lastly, the revision process may include streamlining the language by cutting out unnecessary words and phrases to enhance the conciseness of the writing.
