Hi
May I quote an excerpt from M. Swan, 2005,
Practical English Usage, 3rd edition. OUP. (para. 370.5 "Two negative ideas: not ... or / not ... nor") I posted some months ago in
another thread?
Swan
When not refers to two or more verbs, nouns, adjectives etc, we usually join them with or.
...
However, we can use not after a pause, to separate and emphasise a second verb, adjective etc.
Our main need is not food, nor money. It is education. (More emphatic than ... food or money.)
She didn't phone that day, nor the next day. (More emphatic than ... or the next day.)
Note that neither cannot be used in this way.
In the other thread, I think I learnt that:
1.
neither ... nor ... / not ... or ... are more common in everyday speech -- more "natural"
2.
not ... nor ... (possibly with a comma before "nor") emphasises the second part, so it can be used as a stylistic (formal? rhetoric?) device.
I assume this could explain the number of hits returned by G.Books. Would you agree?
