Reconstructing the Modern South Arabian dual endings
One of the many lovable features of the Modern South Arabian languages is their productive retention of the dual, in nouns, pronouns, and verbs (all persons). Some examples from Omani Mehri (Rubin 2018):
- ġáygi ṯrōh ‘two men’, contrast ġayg ‘man’ (in practice, dual nouns are nearly always followed by the numeral ‘two’)
- perfect bǝg(ǝ)dōh, bǝgǝdtōh ‘the two of them (m./f.) chased’, contrast singular bǝgūd, bǝg(ǝ)dūt and plural bǝgáwd, bǝgūd
- imperfect yǝbǝgdōh, tǝbǝgdōh ‘the two of them (m./f.) chase’, contrast singular yǝbūgǝd, tǝbūgǝd and plural yǝbǝ́gdǝm, tǝbǝ́gdǝn
- independent pronoun hay ‘the two of them’, contrast singular hē ‘he’, sē ‘she’, plural hēm, sēn ‘they (m./f.)’
Let’s look at some reconstructions.
The verb
The verbal dual ending can be reconstructed for Proto-Modern-South-Arabian as *-óh, but its deeper Semitic origin has not been explained. Dufour (2022: 77) writes:
The suffix for the dual in verbs is stressed in MSA (stable in Soqotri). It is unclear what etymon should be posited for it. Akkadian and Classical Arabic have -ā, but such an etymon would not fit the MSA forms since, as we have seen, final vowels drop in Proto-MSA (cf. the exactly identical *-ā suffix marking 3fp in the perfect: Ga *ḳadarā> OMh. ḳədū́r, J./ Ś. ḳɔdɔ́r). On the other hand, Epigraphic South Arabian attests verbal dual suffixes written with a /y/, though what this orthography stands for is unclear. Perhaps we should therefore posit *-ay or *-āy.
Both of these reconstructions run into problems, but I think we can solve those issues by combining both options and reconstructing *-ayā. Consider the following:
First, the final *-h is probably automatically added to a stressed final vowel, or at least to *-ó(h). Rubin discusses this in his § 2.2.4.
How do we get a stressed word-final vowel? Shouldn’t word-final vowels be lost, as Dufour states? Well, if we reconstruct *-ayā, then the first of those two vowels isn’t word-final. Modern South Arabian stress is super weird, but the main rule (for words containing a Proto-West-Semitic low vowel) is pretty much: stress the last, non-word-final *a or *ā. In a reconstructed form like 3m.du. perfect *bagad-ayā, that gives us *bagad-áyā, with the stress in the right part of the word: the suffix.
Next, we have to assume that *-áyā contracts to *-ó(h). *a turns to Proto-Modern-South-Arabian *o most of the time, so this just means loss of an intervocalic glide, something I don’t mind at all. In fact, there’s MSAL-internal evidence for almost exactly the same change. III-y verbs, like *bakay–a ‘he wept’, show up in MSAL as *bokóh (> OMehri bǝkōh). Before suffixes, these verbs retain their y, like OMehri tǝwōh ‘he ate’, tǝwyǝ́h ‘he ate it (m.)’. And, what do you know, so do the duals: “sǝbṭáys ‘they (two) hit her’; śǝnyáyǝh ‘they (two) saw him’”.
The difference in stress in the suffixed forms here is interesting. The 3m.sg. form tǝwy-ǝ́h shows a stressed suffix, part of a paradigm that is only used on the 3m.sg. and 3f.pl. perfects. These are exactly the forms that are reconstructed as ending in a low vowel, *-a and *-ā, respectively (explaining why the vowel right before the suffix is stressed).
Does this show that the 3du. forms did not end in *ā? Maybe. But maybe not. In Jibbali, the stressed object suffixes only occur on the 3m.sg., not on the 3f.pl. (Rubin 2014). As vowel length doesn’t usually play a role in MSAL vowel changes, this is probably due to analogy, the 3f.pl. taking the unstressed suffixes that are used everywhere else in the verb. In the same way, these suffixes could have spread to the 3du., also in Mehri where they didn’t make it to the 3f.pl. So, we could reconstruct the 3m.du. perfect forms as follows:
pre-Proto-MSALProto-MSALOmani Mehri‘they (2) chased’*
bagad-áyā*
bogod-óhbǝg(ǝ)dōh‘they (2) chased him’*
bagad-ayā́-su*
bogod-oyó–

bogod-óy–

The numeral
The number ‘two (m.)’ has what looks like the same ending, as we saw in Omani Mehri ṯrōh. Should we reconstruct this in the same way? I don’t think so; we can get there without the triphthong. Based, in fact, on evidence from Modern South Arabian in particular, this is one of the words where we should probably reconstruct a word-initial consonant cluster in Proto-Semitic: the ‘two’ stem was probably just *θn-, with no vowel. If we add the dual nominative ending, that gives us *θn-ā. While word-final vowels normally don’t receive the stress in Proto-MSAL, here, it’s the only vowel in the word. So without further ado, we can imagine the development as pre-Proto-MSAL *θn-ā́ > Proto-MSAL *θr-óh > OMehri ṯrōh, etc. It’s really striking that the MSAL form seems to go back to a reconstruction with just an *-ā, just like Akkadian šinā. šinā doesn’t inflect for case (as far as I know), which would explain why we don’t get the expected oblique dual ending *-ay(na) here in Modern South Arabian. Adding this to my list of eerie Akkadian-MSAL isoglosses.
The feminine looks a bit confusing but at first sight I would guess it reconstructs to Proto-MSAL *θrót (e.g. Jibbali ṯrut). This regularly goes back to pre-Proto-MSAL *θn-át-ā; here, the dual ending is in a polysyllable, hence unstressed, and therefore lost.
The noun
Nouns mark the dual with a suffixed -i (mostly lost in Jibbali). Unfortunately, dual nouns can’t take possessive suffixes, so we don’t have any allomorphs to work with. Looking at other languages, I think our best bet for the reconstructed morpheme here is the nominal dual oblique ending *-ay. No nunation or mimation seems to follow (maybe because the numeral ‘two’ is always right behind the noun?). I’m not sure if *-ay should yield Proto-MSAL *-i; it doesn’t seem to in the jussive of III-y verbs.
The pronoun
Here are the forms from Rubin’s grammars, independent and suffixed:
Omani MehriJibbali1du.
ǝkáy,
-ǝki(ə)s̃i,
-(ə)s̃i2du.
ǝtáy,
-ǝki(ə)ti, –
(ə)s̃i3du.
hay,
–ǝhiši, –
(ə)šiǝkáy indeed. Mehri gives us some support here for the idea that unstressed *-ay > *-i. Pronouns are generally a pain to reconstruct, because they all influence each other so much. I’ll venture a reconstruction of 2du. as pre-Proto-MSAL *ʔantay, *-kay and 3du. as *say, *-say, wonder out loud what the hell is going on with *k in the first person, and leave it at that.
Summing up
It looks like we can account for the Modern South Arabian dual suffixes by deriving them from *-ay in the noun and probably the pronoun, *-ā in the numeral ‘two’, and *-ayā in the verb. The first two morphemes are pretty much expected as the nominal oblique and nominative endings. For the verbal ending, as Dufour says, usually we’d expect *-ā (or is that too Arabocentric?). That suggests that we’re really looking at a double marking, *-ay-ā, with the dual verb tacking on the nominal oblique (and pronominal) *-ay suffix before the true verbal one. Maybe Old Akkadian, Ancient South Arabian, and Eblaite have some more to add to the story, but for now, this seems double-plus-good to me.
In case you’re confused about the *-s vs. -h, PMSAL *s regularly shifts to h in Mehri. ↩︎#linguistics #ModernSouthArabian #ProtoSemitic
