A quick look at how to use "weder... noch" ("neither ... nor") in German. And a look at the other translations for "neither". With lots of examples.
Right from the start, this root was about the idea:
It has stayed about that in most European languages and evolved into English new, German neu, Greek neo and Slavic novi.
The root is potentially also the origin of a variant *nu, which is where now and the German noch and nun come from, which would make a lot of sense meaning-wise.
