Neither negative is right (3)

I believe the answer is:

nor

'neither' is the definition.
(eg in the phrase 'neither do I')

'negative is right' is the wordplay.
'negative' becomes 'no' (no is a kind of negative).
'is right' becomes 'r' (abbreviation).
'no'+'r'='NOR'

(Other definitions for nor that I've seen before include "Neither pairing" , "And not; Norman (abbr.)" , "Link word" , "In addition, not" , "Word paired with "neither"" .)

I've seen this clue in the Evening Standard.
