There is a simple way to make sure you use neither nor clauses correctly every time.
All you need to do is remember that the first letter in each of the words is an N for not.
In other words, these two words are always negative. The positive form is either and or.
We use neither and nor when we have two negatives that agree with each other. We use either and or when two positives agree or when we have a choice of two things.
It’s that simple.
