Dana'an:
Suppose I say: {wa'Hu' jIghungDI', pItSa' vIvunpu'}, for "yesterday, as soon as I was hungry, I ordered a pizza".
I'm asking this because I understand the klingon as "yesterday, as soon as I'm hungry, I have ordered a pizza", meaning that I "feel" it very close to "yesterday, as soon as I'm hungry, I've (already) ordered a pizza".
Perhaps you could say
wa'Hu' jIghungchoHDI', wejHa' pItSa' vIvunpu'.
to make clear that you have ordered the pizza as of becoming hungry.
Yes, the issue here is that -DI' on verbs expressing qualities often makes little sense, because "as soon as" implies that something happens as soon as the expressed change occurs. jIghungDI' doesn't express a change of state; it only expresses a state, so there's nothing "as soon as" about it. jIghungchoHDI' solves this problem.
A brief glance through canon doesn't bring any quality verbs with
-DI' to my attention, with one exception that doesn't
really count. (paq'batlh has rInDI' as soon as
it is finished, but the verb rIn itself already
implies a change of state to a completion, so it's not a good
example.) One wonders if Q-DI' is another
semantically non-sensible combination in Klingon.
The other issue here is that -DI' doesn't mean "as soon as the action expressed is finished." vIHoHDI' doesn't mean that something happens as soon as he is dead; it means, basically, at the same moment that I kill him. If you want to describe something that occurs upon the completion of the killing, rather than simultaneously with the killing, you'd need to say vIHoHpu'DI'.
So for instance:
jaghwI' vIHoHDI', qabDajDaq jItuy'. When I kill my
enemy, I spit on his face.
and
jaghwI' vIHoHpu'DI', tajwIj vISay'moH. When I have
killed my enemy, I clean my knife.
In the first sentence, I stab my enemy and, as he stares at me with bulging eyes, I spit on his face. In the second sentence, I stab my enemy, then he drops to the ground and dies, and then I clean my knife.
So if we have wa'Hu' jIghungchoHDI', pItSa' vIvunpu',
we're saying that at the moment yesterday that I went from not
hungry to hungry, I ordered a pizza. Again, "moment" in this
context doesn't necessarily mean "instant"; these two events just
happen approximately simultaneously from a human, rather than a
precise, perspective. -DI' doesn't imply precise
simultaneity, just a reasonable approximation. Hey, my stomach is
starting to rumble. Hand me the phone.
