I disagree that quality verbs cannot describe events.

If we look at:

Hogh vorgh jIQongpu'

Hogh vorgh jIroppu'

In both cases, I'm looking back to two events: my sleep and my illnesss, both of which I consider as completed wholes, without inner structure. They were two events that happened last week. Sleeping and being ill are both biological conditions that my body has. Both only last for a certain period of time. Both can be described as events. It's a grammatical feature of Klingon that ghu rop is accepted and ghu Qong is not, but semantically they don't differ much.

Sorry, but no. Having the quality of illness is not an event in the linguistic meaning of that term. Sleeping is. Sure, you can describe them both as biological functions, but that's not the linguistic meaning of the term state, and it's not what we mean when we talk about quality in Klingon.

Now, I'm not saying that Hogh vorgh jIroppu' is necessarily wrong. But what this says isn't that during last week I had the quality of being sick. It says that at some point during last week I experienced the event of being sick, and that the entire event is described in that one sentence. But it remains undemonstrated to me that Klingon allows being sick to be an event, and your simply declaring it so doesn't provide any evidence. The fact is that we have a notable lack of this in Klingon. While that doesn't prove it can't be done, it does prevent you from doing anything to prove it other than to declare it to be so.

Who knows? Maybe there's an unambigous perfective quality verb in canon somewhere that we haven't brought up.
