What is the difference between the negative forms -ず and -ぬ?
-ず and -ぬ are two alternatives to the negative form -ない / -ません. But I noticed that depending on the word, it's either -ず or -ぬ, although it seems like some words can take both suffixes. Some examples I have encountered:
-ず
知らず (lyric in song "タッチ"…

Why is 知りません the negative form of 知っています?
I'm reading Minna no Nihongo (Chapter 15) and it says what I wrote in the question. I would think the negative would be 知っていません。

Why is it なさそう and not なそう
"It seems there is none" is なさそう, which escapes the usual rule for 形容詞 (イ-adjectives), which says "drop the い and add そう".
Is there a historical explanation for this exception? And does it have anything to do with なさいません?

Meaning of ぬ added to 連用形 / masu-stem, as in 風立ちぬ
What does the ぬ at the end of 立ち specify? I can't find a verb that is just 立ちぬ, is this some kind of special form? Can this be done with other verbs as well?
風立ちぬ, for reference, is Miyazaki's new film's name.

Conjunctive form (e.g. 書き) vs Conj + mono (e.g. 書き物)
I'm trying to fully understand the plain conjunctive form without a suffix. I've seen it mainly in the form of 話, where it means a talk or speech. So I think it means something along the lines of "the thing that is produced when someone speaks for a…

About 「同{おな}じ」 and 「同{おな}じく」
As far as I know, 「[同じ]{おなじ}」 is not a 形容詞{けいようし} (-i adjective) so how does it become 「[同じく]{おなじく}」? Or does 「同じく」 not come from 「同じ」?
Also, are there any other non i-adjectives that have -ku counterparts (regardless of the answer for above)?
