In Lingua Latina Per Se Illustrata Pars I, cap. VI it says,
Quam longa est via Flaminia? Neque ea tam longa est quam via Appia.
I am unsure as to how to translate 'neque' here or rather why it is used here. Intuitively, I would translate the response as, 'It is not as long as the Via Appia.' But then why does it say 'neque' instead of 'non'?
