As announced, another post on the books by Ron Ross and Steven Pinker and the primer "How to define Business Terms in Plain English". I'm still at the very beginning of Ron's book, I'm a bit further with Steven Pinker's book.
Steven Pinker's book is about language - as the title suggests. Many linguistic considerations. Ron's Primer and the book have a different focus: How can business communication succeed in "normal" English without misunderstandings?
