Never in the field of human conflict was so much owed by so many to so few.

This is one of the best-known examples of negative inversion in the English Language. And if you're into effective speaking, you'll also notice an example of tripling.
Certificate exams often have a question concerning inversion with negative adverbials, often simply referred to as negative inversion. Students can have problems with these constructions, and for this reason at least one teacher (see link at the end) has publicly wondered if it's worth all the bother, especially as you can speak perfect English without ever using a negative inversion.
But we all like a challenge, don't we? Both you as a student and me as a teacher, so let's have a shot at mastering the little bugger, by taking it nice and slowly. It's only a technique after all; there's no interpretation involved, it's not like choosing verb tenses for example. If you can ask a question, you can do negative inversion. Well, more or less.
There's quite a lot to get through, so get yourself a nice cup of coffee, and when you're sitting comfortably, we'll begin.
