Nor – definition of nor by The Free Dictionary

Usage Note: When neither begins a balanced construction that negates two parts of a sentence, nor, not or, must introduce the second part. Thus standard usage requires He is neither able nor (not or) willing to go. Similarly, nor (not or) must be used to start the second of two negative independent clauses: He cannot find anyone now, nor does he expect to find anyone in the future.
