Pharyngeals, again, and tone, again
My head's really not been in conlanging for the last month or so.
One issue is that every time I come back to this I run up against my own ignorance about how pharyngeals work. I'm slowly working on that, but it'll be a while, and in the meantime I'd really like to be working out other parts of the language.
Here's what I've got so far. (Or what I think I've got---please let me know if you spot anything that seems wrong!) I guess the main single thing I'm drawing on is Moisik's
The epylarynx in speech, but I'll warn you that I've so far read it neither completely nor well.
Anyway, pharyngeal(ised) consonants can be associated both with a distinctive tongue shape and with distinctive epilaryngeal activity.
There are at least two quite different sorts of tongue shape that could be involved. There's the backed/retracted sort, which is what you might associate with an RTR feature, and with vowel lowering in general. And there's the double-bunched tongue that you might associate with one kind of American /r/ (but it's also found in (some?) Caucasian pharyngeals, for example), and doesn't tend to lower vowels so much as centralise and even front them (so you get cases of
a → æ next to pharyngeals, for example).
Anyway the way I've so far pieced things together, it's the tongue shape that's mostly significant with pharyngealised consonants (and I think also pharyngealised vowels?)---which is a reason why some people prefer to describe Arabic emphatics (for example) as uvularised, rather than pharyngealised.
Whereas it's the epilaryngeal activity that's key with full-on pharyngeal (or epiglottal) consonants like
ħ ʕ. These might also involve tongue backing or bunching, but it's less significant (and they often have less of a lowering effect on nearby vowels than do
pharyngealised consonants).
With uvulars I think you often get a split (I'm drawing here on Rose,
Variably laryngeals and vowel lowering). When pharyngealised consonants pattern differently from full-on pharygeal ones,
q tends to pattern with the pharyngealised ones, but
χ ʁ ʀ tend to pattern with the full-on pharyngeals. (iirc, Rose says that
ɴ is too rare to draw any conclusions; I can't remember what she says about
ɢ.)
Glottals can also pattern as pharyngealised in some sense, though obviously they don't have the distinctive tongue shape. (So they won't lower vowels in general; but there are languages in contexts in which all vowels merge to
ɑ under the influence of pharyngeals, and in those languages
h ʔ tend to have the same effect.)
(Sylak-Glassman,
Deriving natural classes, complicates things a bit by considering a much broader range of languages---e.g., it's hard to make sense of Ubykh's
qʲ q qˤ contrasts on Rose's approach---so if this sort of thing really interesting to you then you might want to check out that as well.)
I mentioned epilaryngeal activity. I so far have no head for back-of-the-throat anatomy, and have retained very little of what I've read. The main thing that matters here is that I've convinced myself that it can result in a lower pitch on (the beginning of) a following vowel, perhaps in part by triggering some breathy phonation.
Anyway that's about the context in which I'm now thinking about these things in Nðaḥaa.
The main thing this gives me (it also helps that I've got a better handle on Nðaḥaa morphology) is the confidence to reintroduce a high tone.
I'll sketch the whole system (using nonce roots and affixes).
You might have a root
téáw. (Insofar as it matters, that'll end up getting treated as a single syllable, btw.) And you might add a suffix
-es. The result will be
téáwés---the high tone will spread to the right, onto the suffix. (There's no analogous spreading to the left, onto prefixes.)
A detail: a high tone cannot spread onto a syllable that already has a high tone; and if it spreads to the point where it ends up adjacent to another high tone, the second one will end up deleting. (Like,
qá+ma+téá would result in
qámátea.)
There are certain consonants that block this spreading. These are called depressor consonants, and they include all voiced plosives. So, if you started with
téád, you'd end up with
téádes.
Well, it's trickier than that, since non-root-initial plosives tend to fricativise or even sonorant-ise after vowels, so actually you'd get
téázes or even
téáres. (Which produces some complication, because underlying
z~r isn't a depressor consonant, and won't block tone spreading.)
Anyway, what I've got worked out for now is that
χ ʁ~ʀ ħ ʕ~ʢ h are also depressor consonants.
Depressor consonants can also result in contour tones, at least phonetically. Voiced consonants tend to reduce the pitch at the beginning of a following high-toned vowel; pharyngeals and
h tend to lower the pitch at the end of a preceding high-toned vowel. I'm not going to worry about representing this orthographically, though.
One thing though: it seems reasonable to stipulate that there can't be a high tone on a vowel that's preceded by a voiced consonant and followed by a pharyngeal or
h. E.g., you could have
dá and
táh, but you can't have
dáh.
A bit more about vowels
One thing: I've decided that the syllable template allows for two vowel slows. This allows for both long vowels and opening diphthongs.
This means that I've talked myself into a four-way contrast between
i ij ii iij. I can live with that, partly because that
j is actually
ʑ~j, and I could assume it's somewhat fricated in this context.
A consequence:
nðaḥaa will contrast with
nðaḥaʕ, so I have to decide once and for all which it is.
Anyway there are four vowels, which I've been thinking of as
i e a u~o. But there are a bunch of consonants that affect vowel quality.
- The palatals ɲ tɕ dʑ ɕ ʑ~j tend to front preceding vowels.
- The pharyngeals χ ʁ~ʀ ħ ʕ~ʢ tend to lower preceding vowels.
- The pharyngealised consonants ṇ ṭ ḍ ṣ ẓ~ṛ tend to lower both preceding and following vowels.
Note that a vowel that follows a pharyngealised consonant and precedes a palatal one will be both fronted and lowered.
The result is the following four systems of vowel contrasts:
| i | e | a | u~o |
neutral | i | e | ɐ | u~o |
fronted | i | e | æ | y~ø |
lowered | e | æ | ɑ | o |
fronted+lowered | e | æ | æ | ø |
Phonologically the main point of interest is that the
e a contrast is lost between a pharyngealised consonant and a palatal: there's no distinction between
ṭaj and
ṭej, for example, both would end up as
ṭæj.
I'm going to keep the orthography simple, though. (I'll continue to write
u~o as
o.)
Coda
This is, at least, I hope, enough to go on with.
The next post will be about something non-phonological, I promise.
