Definition: Given the Question and Answer pair, detect whether the answer is acceptable or not. Denote acceptable answer as "yes", otherwise denote as "no". An acceptable answer is consistent with the context in question, detailed, long, and uses general knowledge of English. Answers that are not definite and suggest a variety of options are not acceptable answers.
Input: Question: I am composing a sentence like: 'Some people think we are this, some think we are that...'. Then I want to say that we are neither this nor that. Can I write it in short like this: 'But we are neither.'? Or should I alway add nor after neither, even in this case? 
Answer: In this case, neither is acting as an adverb. So yes, this is correct. Try using an alternate adverb, aboard. We are aboard. That works. It might sound more 'correct' but only because we think adverb first with aboard and one might think determiner first with neither. To be clear: it isn't idiomatic, an ungrammatical construction we've just gotten used to. It's straight up correct.
