(KGT 28f.): The standard word for this prominent part of Klingon anatomy is Quch, and this word is found with this meaning throughout the Empire. In addition, however, practically every dialect has its own alternate word for forehead. Indeed, Quch is simply the word for forehead in the First City. Among these other forms are: boD, jargh, mIQ, 'aQlo', Huy'Dung, tuqvol, no''och. While the first four of these words are simply regionalisms for forehead, the last three can be analyzed, at least partially. Huy'Dung is probably from Huy' Dung ("above the eyebrow[s]"). The word tuqvol may contain the word tuq ("house [lineage]") because family resemblances can be seen in forehead ridges. The second element, vol, however, is otherwise unknown. Similarly, the first syllable of no''och may derive from no' ("ancestors"), again suggesting something about genealogy. The second syllable, 'och, probably resembles 'och ("tunnel") only accidentally; there is no reason to think that "ancestors' tunnel" is a way to say "forehead".
