This is where I will check the fine details such as your spelling, punctuation and grammar, ensuring the correct use of words, and the consistency of your argument or story line if not already dealt with at the developmental stage. You may have inadvertently deviated from the expected course, due in part to the sheer number of small details you are trying to incorporate into a single, cohesive narrative. Inconsistency in spelling will also be caught and picked up in sentence-level editing so you, the author, can be alerted and be able to promptly correct it in the next draft. I will make sure you can see all of these corrections.
