“I was working on the proof of one of my poems all the morning, and took out a comma. In the afternoon I put it back again.” ~ Oscar Wilde

Proofreading, are you ready? Proofreading is the overcoat sealing a polished work. It focuses on errors a computer might miss to ensure no spelling or grammatical errors AFTER the document has AlREADY been developmentally and copy edited.
Copyediting is what it is; it doesn’t change based on light, medium, or heavy. The use of the terms light, medium, and heavy can be problematic because clients and copy editors may possess different concepts of their definition.
Light copyediting might consist of double-checking accuracy and taking care of most grammatical issues. Medium copy editing includes heavier lifting, such as correcting flow and re-working some of the text. With heavy copy editing, the editor might re-structure some paragraphs, or heavily correct style, flow, and grammar.

Developmental editing (aka content editing ) is intended to deal with structural problems. Developmental editing is much more intensive, which may involve things that were left out, or sections requiring a complete re-write of content. This includes some level of content creation along with making corrections.
