{yIH nuq} works because {nuq} sort of works like a pronoun, except when it doesn’t.
It always works like a pronoun. Pronouns have two functions in Klingon: they stand in for nouns (nuq legh yaS), and they help identify nouns (yIH nuq).
I doubt nuq does all the things that pronouns can do. I
doubt, for instance, that you'd ever put verb suffixes on nuq.
I don't think yIH nuqbe' What isn't a tribble? is
a well-formed sentence. We don't really know anything about that.
But nuq always functions basically the way a pronoun
functions in Klingon.
Considering that the correct answer would be {Ha’DIbaH ‘oH yIH’e’} it’s pretty clear that {yIH nuq} is probably a shortened version of {nuq ‘oH yIH’e’}. The word {nuq} absorbs the meaning of {nuq ‘oH}, and with a single noun combined with the resulting chuv acting as a pronoun, the noun comes first.
"Pretty clear"? The ONLY evidence I can think of to support
anything like that is the clipped version of nuqDaq 'oH
puchpa''e' turning into nuqDaq puchpa'. One single
sentence using a different word isn't what I'd call "pretty
clear." It's a possibility only. We have evidence against that
claim, in that Okrand said the word nuq works "the same
way pronouns do in questions with 'to be' in the English
translations," and says that yIH nuq is exactly parallel
to yIH 'oH. That explanation contradicts the Clipped
Klingon suggestion.
We don’t say *{nuq yIH} for the same reason we don’t say *{maH tlhIngan}. When one noun forms a sentence with a pronoun, the noun comes first.
Except we have nuq mI'lIj, tera'ngan from CK. I've also
internalized that we have both SoH 'Iv and 'Iv SoH,
but I can't find a source for 'Iv SoH, so that may not be
a canonical sentence.
