 Re: Neither do we need a parking area.
Many adverbs which have a negative or "limiting" meaning cause SV inversion when they are at the beginning of the clause. Other examples : Never have I been so embarrassed; Not only did we lose our money, they also took all our credit cards; Hardly had I spoken when he walked in; We couldn't do it, and neither could the teacher!
The same happens with so: So badly did he fail, that he never wanted to try again; I like chocolate and so does David.
This is not a question form, just a second use of inversion (a third is "conditional "inversion - Had I known, I would have stayed at home! ).
The reason why need we doesn't work in that sentence is different. Need has two constructions. It can be a main verb - We need / Do we need/ we don't need - or a modal auxiliary - We need, we needn't, need we . But obviously, as a modal it can only be followed by another verb, not a noun. So, Neither need we cheese is not possible but Neither need we worry ... is fine : We needn't worry about cost and neither need we worry about maintenance. |
