vIqawchu'chugh, ngIq was introduced at a qep'a' where Okrand asked Klingonists to look over the text of the opera 'u' that he'd translated, and discussion of new words was done entirely in Klingon. My guess is that nobody asked Okrand for more detail because they assumed they had it figured out from the examples even without a precise English gloss. Same with the question of number agreement with conjunctions -- people probably just went with what felt right without thinking of it as something worth asking about.

 

It's possible that the people who have Okrand's email address don't think the questions are that pressing. It's also possible someone's already forwarded them to Okrand and we'll get answers in November. It'd be nice to have these questions answered. But I'm not the one who has to put time and effort into answering those questions, nor am I the one who has to directly ask Okrand for his time and effort, so I'm less inclined to demand that others do those things on my behalf.

 

If I put my mind to it and I had a week to kill, I could probably come up with a hundred grammar questions. "How do we use this word" and "can we retcon this goof into grammatical Klingon" and "what is the preferred style or phrasing in this sentence" and "would this construction be interpreted the way I meant it to be interpreted" and so on.
