At first glance, it looks like a verb-final language with noun-adj order, i.e. nothing wild out - but it is something entirely different from *any* human language.

And it is something entirely different from saying "verb-final, postpositional, noun-adj order" even though simple sentences look like that. It is a grammar wholly outside the range of grammar types found in human languages. I once had an idea of an interlanguage humans and Fithians could use to communicate with each other. I called it "Shallow Fith". Basically, it is a proper subset of Fith, with strict limits to stack depth and most of the stack operators of Fith removed. The Shallow Fith sentences could be parsed as SOV/postp/noun-adj sentences by humans and as very simple LIFO sentences by Fithians. Here is what I wrote about it in a never-published web page a few years ago:
>>Shallow Fith is a subset of Fith. We are leaving the ground of
Jeffrey Henning's original creation here; this is my own invention. In the fictional universe which Fithia is part of, it has a well defined purpose: that of an auxiliary language meant to facilitate communication between humans and Fithians. As said above, Shallow Fith is a proper subset of Fith, which means that any grammatically correct utterance in Shallow Fith is also correct in Fith, having the same meaning in both. Shallow Fith, however, differs from Fith in being more restrictive in grammar, in order to restrict the depth of the stack during parsing sentences. (Hence the name _Shallow_ Fith.) In fact, the stack depth is restricted to such a degree that human minds can learn to comprehend Shallow Fith in real time. Shallow Fith eliminates most stack conjunctions and heavily restricts the use of the remaining ones: * _du_ must immediately precede a verb or a postposition, thus acting as a reflexive pronoun only; * _shen_ must also immediately precede a verb or a postposition; * _e_ and _frong_ must immediately follow the clause they pop from the stack. All other stack conjunctions simply do not exist in Shallow Fith. Furthermore, lingering is not allowed. Sentences must linearly follow each other, as in human languages. To a Fithian, Shallow Fith seems like poor style, something like child-talk, lacking any kind of stylistic sophistication. To a human, however, this is what makes it understandable in the first place. And after all, no-one really asks about beauty in this kind of language anyway. It is just a practical tool for a practical problem.<< I am not sure how that would work out, though. Any opinions?

Exactly. Leaving things on the stack for later usage is indeed a common rhetoric device among the Fithians. It is called "lingering". Greetings, Jörg.
