Oxford Editing enjoys helping others master the English language. Our editors will often take the time to explain grammatical fixes, and we hope that our clients learn from the editing process. Our lead editor, Matt J. Duffy, offers a "crash-course in good writing" to all his college students. Feel free to print it out for your personal use:
Duffy also enjoys explaining grammar rules via video. Below are a collection of his video grammar tips. Please email if you have a vexing grammar question that requires a video answer. Don't forget to suggest a locale!
