"or" in English is actually logical xor, which means that when we actually need to express logical or, we have to implement it in terms of other operators; hence "and/or", i.e. "and xor xor"

Finally, xor, which we can build from and: "soup or salad" becomes "neither (soup and salad) nor (neither soup nor salad)" which is actually pretty readable!

of course, using "and" is kind of cheating; if we really want to use just "neither", then we have to write: "neither (neither (neither soup nor soup) nor (neither salad nor salad)) nor (neither soup nor salad)"
