I was confused when I first encountered the word <yID> in Klingon. I could not find it anywhere in the Klingon dictionary. Then, it suddenly dawned on me what <yID> has to mean. Then, I used it as a noun in the sentence: yID jIH je And, someone replied that <yID> is only a stative verb and that I should have written: jIyID. Please clarify which part of speech this coinage is.
