Looking at the actual examples, certain adverbials appear to consistently precede other particular adverbials. That looks a lot like the behavior of verb suffixes.

We don't have enough examples to form a pattern. We have a few examples from paq'batlh.

There is no evidence that the order of adverbials depends upon their relative “importance”. We don’t even know how a Klingon would rate the relative importance of adverbials.

Or whether there is a fixed order at all. Or whether the order determines some kind of scope. Or whether certain adverbials precede other adverbials on Tuesday nights when you have two jacks.

There is limited evidence that there is a kind of nesting such that each adverbial applies to all that follows it, though it could well be that the sequence is arbitrary. Meanwhile, he could have shown us that it is arbitrary by varying which adverbial comes first, but he didn’t, so it seems less likely that it is arbitrary.

He wasn't trying to show us that the order was variable, he was translating poetry. And when people write or speak, they often don't vary something that could be variable because consistency helps keep the narrative together. They're not "Jane and Dick" books, even though there's no linguistic reason not to call them that. It's not "Costello and Abbot" or "jelly and peanut butter."

It would be interesting if someone were to bring up the idea of adverbial types to Okrand. I suspect he’d smile at the idea. He might go with it, though I doubt it.

If he did, he’d probably go back and study the patterns he’s already followed, then expand on those patterns with ideas of his own and we’d have another little interesting tweak to the grammar of the language.

But, as I said, he probably would just smile and not offer us any further insight.

I dislike speculating on when Okrand will act impishly or not. Imagining mysterious smiles does not substitute for analyzing grammar, and any speculation on what he would do is just so much fan fiction.

Any opinion the rest of us might form can color our individual approach to the language, but will not become commonly accepted practice by the body of speakers.
