Beku and bekarazu, I don't get how the zu form even become like that or am I thinking of two different verbs?


I was looking at a website for beku and bekarazu, however, I think bekarazu is
the zu form of beku and it just doesn't make sense. I would make it べかず
instead of べからず because it appeared on a website that the zu form is just the
negative form, but instead of nai, zu is attached to the verb. Can someone
answer my confusion?




べく is the adverbial form of べし, which is, as a 形容詞, also regularised to べい
dialectally. べからず simply consists of べく＋あらず, the latter being the verb in use,
ある, in its classical negation. Compare and contrast to modern past positive
～かった, which is itself ～くありたり.
