I think DungluQ is the first word that I've seen that incorporates a lone g .
Except it's not. The first syllable is Dung and the second syllable is luQ.
Ok. Can this word be broken down and analyzed?
Not really. There is also a word Dung which means "area above", but it does not seem to be related and we don't know of any root luQ.
The Latin letter g is here part of the digraph ng, which is one Klingon letter.
I'm sure you've seen the letter ng before in words such as tlhIngan or tera'ngan.
