What is the difference between developmental & substantive editing?

Hi Victoria—You have really good information on your website. After looking around, I have a question. What exactly are the differences between developmental editing and substantive editing? Jake

Thank you for your kind words, Jake! There’s a really good reason I don’t use the term ‘substantive’ in discussing editing: it is the most confusing term used by editors to describe the different types of work we do.

When an editor talk about ‘substantive editing’ they can mean anything from developmental editing—designing and structuring a story or book—to line editing—polishing the prose.

Some editors mean one or the other.

Some mean both.

Just about the only thing they all agree on is that substantive editing is not copy editing—making the prose conform to the grammar and punctuation rules of the reader’s native language (different, for instance, in the US and UK)—or proofreading—checking for typos.

So I use ‘developmental editing’ when I address the way a story or book is put together.

And I use ‘line editing’ when I address the language.

I don’t use ‘substantive editing’ at all.

‘Substantive’ means, really, an independent identity. I don’t honestly know how that word got tangled up with editing terminology throughout the eras in traditional publishing.

By ‘substantive’ editors mean ‘substantial,’ in which the editor makes substantial changes and alterations. Some editors confine themselves to discussing each individual issue with the writer. Others work with the writer to arrange the story or book in the way that will convey to the reader most clearly and powerfully the writer’s vision and then polish the resulting manuscript for professional language.

It depends entirely upon the editor’s own definition.

The British editor Diana Athill even confesses in her marvelous memoir Stet that she was not above adding jokes.
