Proofreading vs editing

It’s very common to get confused between proofreading and editing. Proofreading refers to locating punctuation and grammatical errors and amending these. Editing, on the other hand,  usually requires an expert who will provide suggestions to improve the quality of the writing, particularly related to expression and language. An editor will also make any necessary changes to the writing too.
