I had a date with her next day at 2.15 P.M. in my own rooms, but it was less successful, she seemed to have grown less juvenile, more of a woman overnight. A cold I caught from her led me to cancel a fourth assignment, nor was I sorry to break an emotional series that threatened to burden me with heart-rending fantasies and peter out in dull disappointment. (Lolita - Vladimir Nabokov) This is perhaps a strange question, but is Nabokov's use of 'nor' common? I mean, 'nor' is usually preceded by a negative idea involving either 'neither' or 'not'. For example, these example sentences come from the Longman Dictionary of Contemporary English: Hilary was neither shocked nor surprised by the news. It was not my fault, nor his. They couldn’t understand it at the time, and nor could we. (Longman Dictionary of Contemporary English) But in Nabokov's sentence we have neither 'neither' nor 'not'. Instead we have 'cancel' which is different. What do you think? Thank you in advance.
