[tlhIngan Hol] thoughts on the verb {nI'}

There's the verb {nI'} "be long, lengthy (duration)"; so the question is "what does it take as a subject"? A little bird told me, that there's the paq'batlh example of {Qobbogh may' nI' jun}, which shows that the {nI'} *can* take an event as a subject. So, so far so good.. But this led me to wonder.. Could the verb {nI'} take as a subject the noun {poH}? And if yes, then what would be the difference between {poH nI'} and {poH vItlh}? ~ Dana'an an alien language crawling with terran puns; hahaha
