Someone (Visirius) posted this about ablaut reduplication on the Klingon Discord recently and it seems relevant to {vIqraq}:
Does Klingon also follow this pattern? That is, are there words that sound like *{vaqrIq} instead? The only one that comes to mind is {raS'IS} (which is not *{rIS'aS}).
I don't know about this particular rule, but I do know that Okrand has given such things thought. We have the words Dung area above and bIng area below, which sound exactly backwards to an English-speaker's ear (which tends to have front-vowels for up and back-vowels for down). I believe Okrand confirmed — though I cannot cite a source; it may have been a conversation at a qep'a' — that he did this intentionally.
It's also possible that Okrand doesn't know about ablaut
reduplication and lets his English bias bleed into Klingon.
