In copy editing we review and correct subject/verb agreement. We check numbers, tables, figures sequencing and the match in the list, fix inconsistencies in capitalization, parallelism, number styles and abbreviations. Check all grammar and punctuation throughout the file. Change standard misuses: which/that; since/because; while/although or whereas etc. Ensure that all references follow correct style format and query for any missing elements. Eliminate sexist language and explain nonstandard acronyms and abbreviations at first mention.
