Vædty Qyṣ, some diachrony
It looks like Vædty Qyṣ is going to end up at laest substantial enough for Akiatu's ancestors to acquire vocabulary from it. And since Akiatu's been in search of a verb-final language to give it some verbalising morphology, it's looking like Vædty Qyṣ is the donor. So maybe Vædty Qyṣ should have its own historical depth.
Anyway that's what this post is about. Mostly it's sound changes, though I'll also show how the sound changes give me about the plurals I want.
The sound changes are kind of dull, mostly unconditional, but they result in fairly drastic superficial changes (and a few not so superficial ones). My current thinking is that grammar will mostly not seem to change so much. (A factor is that the sound changes are boring enough that even without much analogy they wouldn't substantially disrupt the languages's agglutinative tendencies.)
Let's say the time depth is something like 500 years.
Qɨsə basics
Qɨsə (that's what I'll call the parent language) has a somewhat simpler inventory than does its Vædty descendent:
That's to say: no retroflex or labialised consonants, and there's a genuine series of voiced plosives; and there's
p but no
h.
There's contrastive length on all vowels. Epenthetic
ə is also common, it's inserted to preserve a simple syllable structure.
In transcribing historical forms I'm going to follow the IPA strictly, forgetting the conventions I've been using with Vædty Qyṣ itself. I'm also not going to worry about when
r acquires its [r~l] allophony, maybe it's already there in Qɨsə.
Syllables can be CV(C) or CrV(C); the first consonant in a complex onset must be a voiceless obstruent, and a coda consonant must be resonant (including
ɾ). I'll write the rhotic in complex onsets as
r, but there might be morphophonology that erases the
ɾ/
r distinction in this context.
Phonotactics are enforced by insertion of
ə, scanning from the right, much as happens in Vædty Qyṣ itself, though the rules are a bit different. (The differences: allowing
Cr onsets but disallowing
FC ones, and disallowing coda fricatives.)
I don't think there'll be major differences in prosody: final stress, unstressable clitics, boundary tones, and pitch accents. (Which is not to say I've worked out the actual melodies, or that they couldn't change.)
Sound changes
First are a bunch of changes that upset the consonant system somewhat:
- p → b / V_V (including between epenthetic vowels)
- p → f elsewhere
- fr → fʷ
- tr → ʈ
- sr → ʂ
- kr → kʷ
- qr → qʷ
At this point we start getting interactions between the retroflex consonants and the uvulars. I won't try to figure out the details, but there's one change that'll probably be fully general (since it's needed to derive the name of the language!):
The
ə in the context will always be epenthetic, so you could take it to represent the lack of an underlying vowel between the consonants.
Possibly overlapping with that first set of changes is a long pull chain shift among the short vowels.
- ɐ → ɑ
- ɛ → æ
- i → e
- ɨ → i (except after retroflex consonants)
- u → ɨ / _C[coda], C[labialised]_, C[retroflex]_, q_, _q
At this point, vowel-harmonising shifts of suffixed
ɑ to
æ can get started. Accompanying this, you'll get sporadic
æ →
ɑ in suffixes. (Which is to say, you'll increasingly get
æ in suffixes _only_ as a result of harmony.)
Next you get merger of the nonlow central vowels:
The most significant part of this change is that, like former
ə,
ɨ and former
ɨː now get reanalysed as epenthetic. This means that where they are not phonotactically required, they get dropped. Note that this takes place
after obstruent+rhotic clusters have finished changing into no phonemes: Qɨsə phonotactics no longer allows onset clusters (but it does still allow resonant coda consonants).
Now it's time for the voiced fricatives.
Starting with these changes, syllable structure can begin to shift to allow both coda fricatives and fricative + plosive onsets. Given how many vowels are epenthetic, this can quickly affect the syllabification of many words. E.g., with this change, there's no longer any need for an epenthetic vowel in (a hypothetical word)
vɨka, so it will become
vka.
The last change among the consonants is the loss of remaining
f (which should only occur morpheme-initially):
Finally, vowel length gets lost:
- iː → i
- uː → u
- ɛː → e
- ɔː → ɔ
- ɐː → ɑ / q_
- ɐː → æ elsewhere
Here's how these changes apply to
prɛdɨtə qɨsə:
- → prɛdətə qəsə (merger of short ɨ with ə)
- → frɛdətə qəsə (p→f)
- → fʷɛdətə qəsə (fr→fʷ)
- → fʷɛdətə qəʂə (s→ʂ/qə_)
- → fʷædətə qəʂə (ɛ→æ, the vowel chain shift)
- → fʷædɨtɨ qɨʂɨ (raising of epenthetic vowels)
- → væðɨtɨ qɨʂɨ (fʷ→v, d→ð)
- → væθtɨ qɨʂ (more complex syllables now allowed, some epenthetic vowel are lost)
- → Vædty Qyṣ (Vædty Qyṣ orthographic conventions)
Plurals
The description I gave of plural formation was meant to hint at historical depth. Now I'm in a position to fill in those hints a bit.
In the parent language Qɨsə, there are two main strategies for forming plurals.
The first lengthens the final vowel in the stem, and appends a short echo vowel if the stem is consonant-final, and otherwise appends nonsyllabic
u after a back vowel and nonsyllabic
i otherwise. On the way to Vædty Qyṣ, analogy keeps the echo vowels in harmony with the lengthened stem vowels, which in turn do not undergo the chain shift, resulting in alternations.
For example:
- prɨkɨtə tree → prəkətə → frəkətə → fʷəkətə → fʷɨkɨtɨ → vɨkɨtɨ → vkɨtɨ <vkyty>
- prɨkɨːtɨ trees → prəkɨːtɨ → prəkɨtɨ → frəkɨtɨ → fʷəkɨtɨ → fʷəkiti → fʷɨkiti → vɨkiti → vkiti <vkiti>
The result are a good number of words in which the vowel alternates in the plural, much as I described in the earlier post.
The way analogy affects these plurals is going to be complicated. There'll definitely cases in which nouns with alternating stems settle on a single vowel quality for both singular and plural forms. But the alternations will also be common enough to be the basis for analogy, so there'll also be nouns that acquire a change in vowel quality in the plural. It'll be a bit messy, with room for lots of variation amoung speakers/bands, but nothing terrible.
The second way to form plurals in Qɨsə is by means of certain augments. These may go back to a noun class system or something, but in Qɨsə itself mostly play a role in noun→noun derivation. Some of these have a collective or plural or indefinite sense, and some nouns form their regular plural in part by using one of these augments. Moreover, the augments themselves are mostly of a CV shape, and mostly add nonsyllabic
u or
i as a plural marker, without any lengthening of vowels.
I think in Qɨsə itself there were a few of these augments that showed up semiregularly in plurals, but the system got simplified a bit, and only
-kɐ survives into Vædty Qyṣ. In actual plurals, it would be
-kɐi̯, which in Vædty Qyṣ ends up as
kɑi̯ <kaj>. Meanwhile, whatever non-plural uses
-kɐ had in Qɨsə have mostly been lost, so
kaj as a whole comes to be thought of as the plural marker.
A consequence. As I work on Qɨsə more, I'll probably end up with some semantic classes within which nouns tend to get the
kaj suffix. We'll see.
Coda
That's mostly it for now. Some little thoughts about how this affects other things I've covered:
- I designed the case system with the thought that different cases and postpositions were grammaticalised to different extents, and now I've got more of a framework in which to think that through. One possibility is that one or more of the noun augments I mentioned above could have gotten incorporated into the case system, though I don't know how well that would play with my decision to make the noncore case markers clitics.
- I have no plans to derive the agreement markers from full pronouns, at least until such time as I go further back in the history of the language. Maybe though the subject agreement suffixes, the possessor agreement suffixes, and the object proclitics will look more similar to one another in Qɨsə.
- The Vædty Qyṣ copula looks a lot like its definiteness marker. This is actually a coincidence, but it looks like it might be possible to give them a common origin, with the definiteness marker being sə and the copula being sri, with the shared s maybe having a demonstrative sense.
- I don't currently have any useful ideas about the past tense marker, negation, or the various clitics I've discussed. Or the future. I think at least the past tense marker and the negator are very old. But my plan is to focus next on participles and other somewhat deverbalised forms, and there'll be room for Vædty-specific innovations there.
- I guess Vædty itself is a name for one of the regions where Qɨsə was spoken or to which its speakers migrated. There'll be other such regions, and thus other Qɨsə languages. One of these days I'll have some fun doing comparative work in this little language family.
Edit. I ended up doing a bunch of edits. Some were just to fix dumb mistakes. The biggest problem, though, was that I'd ordered various changes so that Vædty Qyṣ
i could only derive from a Qɨsə long vowel, and I decided I didn't like that, so I reordered things a bit drastically.
Also, the more I play with things in a diachronic context, the more it looks like I'm going to want to adjust things. No surprise there, I guess.
