ok, thanks; however another question came to mind:

I understand why the {Dochmey mI'} is wrong/inappropriate for the
intented meaning. But what if I wrote {Dochmey HochHom} for "almost
all of the things" ? In this example, is the {HochHom} the head noun
too ?

Yes. Technically, if I said Dochmey HochHom vISay'moHta' I cleaned most of the things, I'm saying I cleaned "a majority." A majority of what? Things. It's a "thing-majority," which is a kind of majority, not a kind of thing.

It gets confusing because in English we say "most of the things," wherein most is not a noun. But Klingon expresses this in a noun-noun construction, so the grammar is different. The Klingon kind of looks like HochHom is acting like an adjectival verb, but it's not.
