About the usage of ’and neither’ / ‘and nor’, I’ve found following sentences in ‘Longman Dictionary of Contemporary’ and ‘Collins Cobuild advanced learner's English dictionary’;
1) I don't expect children to be rude, nor do I expect to be disobeyed.
2) They couldn't understand it at the time, and nor could we.
3) Tom didn’t believe a word she said, and neither did the police.
4) The authorities were not sympathetic to the students’ demands, neither would they tolerate any disruption.
5) If politics did not interest them, neither did they see it as affecting their lives.
6) I don't want to see him go and nor do the fans.
7) He doesn't want to live in the country when he grows up, nor does he want to live in the city.
8) I never learned to swim and neither did they.
9) I don't have all the answers and neither do you.
Then, I have following questions and I’ll appreciate on your kind explanation;
1. In the pattern of ’not ~ and neither’ / ‘not ~ and nor’, ‘neither’ and ‘nor’ are always interchangeable? Some people say, ‘nor’ is the correct choice here and we may say 'and neither' instead of 'nor'.
2. Can I understand that we should add ‘and’, when the two subjects in each clause are different?
3. The ‘nor’ in above 1) is a conjunction, while the ‘nor’ in 2) is an adverb because ‘and’ already exists?
Thanking in advance,
