I suppose, since nobody is listening, I might as well tell you the ideas behind the language.
This is supposed to be an old
language. The Time Lord civilization was around since the beginning of time or so, so it makes sense that its language would be pretty old too. There is such an annoyingly long case list because of this; all prepositions (save one, which mutated into a conjunction sort of thing) agglutinated onto the nouns, and were eventually systematized. And, of course, it is fitting that one of their primary cases would be the temporal case, to tell when something happened. This mass of inflection is balanced out by the unsophisticated verbs, which once again demonstrate the nature of the Time Lords in that it is the future tense that has the most aspects.
The fact that their numbers go through singular, dual, trial, all the way to 5,764,800-al I have no excuse for (their numbers are known to be in base seven though); although, they would have to be precise for all of the engineering they have going on. If I were to transpose this into a phonology, though, I'd say that in the most commonly spoken dialects, the only concrete number is the singular, and the others are all just the names of the numbers that agglutinate onto the beginning of nouns and pronouns. Word order I want to leave to your imagination, as I do not want to think too hard about the whole issue of relative clauses going sideways and things.
I decided to make articles wonderfully weird in this language, following a different path than any language on Earth (or so I think). I like the idea of pronouns having articles, and furthermore these articles indicating the case of a given pronoun (I hate having an oblique case in any language because it is so vague, but I had no problem using it here because the uncertainty is corrected by the article).
Who knows, someday I might invent a phonology and a verbal vocabulary for this, but I don't want to make it too definite a language, because then it loses its mystery and ability to be retconned, two characteristics that are essential to anything related to Doctor Who.
I think I'll wrap it up here; lastly, an imperative example asked of me by a person on Gallifrey Base:
(he asked for "#### biscuits"; here's the gloss:
PRS.IMP-####-GNO a-ACC biscuit-ACC-PAU)
My native language is Hungarian, so it's hard to surprise me with any of your grammatical aspects! (Not literal grammatical aspects, as Hungarian doesn't have ANY.) Also, I consider myself fluent in Latin and English.
