For that matter, {‘opuH} is somewhat uncommon in terms of phonemes, in that the {-opu-} would more commonly be {‘o’pu-} or {‘op’u}. The syllable division in Klingon is usually between two consonants. So, is this {‘op-uH}, or is it {‘o-puH}? Where do you divide the syllables? It’s like the {p} is the syllable boundary, making it somehow not quite belong to either syllable.
I’m don't feel sure I really know how to pronounce this simple word.
