Thank you SuStel for taking the time to explain all this. Reading your reply, I realized many things, which I've ignored before. But before leaving this thread, I'd like to write some thoughts, on how I understand the use of aspect on verbs expressing qualities, when they are used before or after another verb with the {-taHvIS}. Now, don't misundestand me; I remember that you wrote, that you don't want to go into another conversation, about what perfective might mean on verbs expressing qualities. And I'm certainly not trying to draw you into such a conversation, although - to confess my sin, - I'd really love to.. But I'd like to write some thoughts, expressing my understanding (or total lack of..) on this matter.. After all, due to the severe restrictions, which have been placed in greece due to the coronavirus, I need to do something since staying indoors can become quite boring.. Anyways.. After reading your comments on the sentence {nyuyorghvo' *colorado*Daq jISeDtaHvIS vIghro' vIlegh}, I've wondered three things: 1. Do these comments apply for quality verbs as well ? 2. Do these comments apply if instead of the {jISeDtaHvIS}, we had a duration of time ? e.g. {qaStaHvIS wej rep}, as in the example of my first message ? 3. How do the conclusions drawn from your comments on the sentence {nyuyorghvo' *colorado*Daq jISeDtaHvIS vIghro' vIlegh}, influence my understanding on the sentence {wa'Hu', qaStaHvIS wej rep, jIQuchpu'} ? As far as questions 1 and 2 go, my answer is "yes", since I can't see a reason why things would be different with regards to be-verbs, or in the case where we wouldn't have a {jISeDtaHvIS} but a {qaStaHvIS wej rep} instead. So, I come to the sentence of the original post {wa'Hu', qaStaHvIS wej rep, jIQuchpu'}.. The way I understand this, writing {wa'Hu', qaStaHvIS wej rep, jIQuchpu'} means that: "..I'm here today, looking back on the day before. Then, there was a duration of three hours, and during that period of time I've been happy.. My happiness didn't last three hours; it lasted a period of time which is unspecified, but surely less than three hours.." I've wondered though, what the meaning would become if the same sentence, was to be interpreted from the "historical presence tense of english". And I came to the conclusion, that in this case, the meaning would become: "..I'm in the yesterday as it's unfolding, in the three hour time-span, but now my "having been happy" has taken place and has been completed before the commencement of the three hour time-spam.." Granted though, there's something strange with the above interpretation; if my happiness took place before the three hour time-span and has been completed, then how is it possible that it will be remaining completed only during that period ? This interpretation, gives the impression, that after these three hours my "having been happy", is somehow undone. Anyways, moving on, another question which troubled me was, what does writing {wa'Hu', qaStaHvIS wej rep, jIQuch} mean ? And after reading your comments on the {jISeDtaHvIS} sentence, I came to the conclusion, that it means one of two things: If the sentence is to be interpreted from the "looking back on events of the past" point of view, then it means "yesterday, during three hours I've been happy from time to time". And if the sentence is to be interpreted with the "historical presence tense of english" (or greek), it means that I'm standing in the yesterday, within the three hour time-span, and within the moment/moments during which I'm happy. So the final question arises: How the jay' do I say that "yesterday, my happiness lasted three hours" ? And the *only* way one can say this, is by use of the {-taH}: {wa'Hu', qaStaHvIS wej rep, jIQuchtaH}. Interestingly though, regardless whether the meaning of "yesterday, my happiness lasted three hours", would be given from today's-looking-back-point-of-view, or from the "historical present tense" of english point of view, the klingon sentence would remain the same, thus leaving things to context to clarify how the story is narrated. ~ mayqel qunen'oS
