Prehistoric isoglosses in Proto-Steppe

As you can see, I've been pondering on Proto-Steppe today. Many people refer to this early hypothetical language set most sensibly around 9,000 BCE as Indo-Uralic and it's called this because it's the common ancestor of both Proto-Uralic (PU) and Proto-Indo-European (PIE) afterall. However I still prefer my own term Proto-Steppe a) because it's more descriptive of the likely region where it was spoken and b) because PIE and PU aren't the only language groups implicated in the grouping. I made this simple isogloss map to show at a glance how I would explain Proto-Steppe's development into the later proto-languages known and studied and it relates, as always, to the unpixelated view of the Wave Model of language change. Thus far, I've been satisfied with a 4-vowel system of *a, *i, *u and *ə, forming a pleasant V-shape when you graph it out on paper using the dimensions of height and backness. V-shaped vowel systems are quite common around the world as far as vowel systems go.

Now to explain the three isoglosses I have on display above. I've been getting the impression for a while that Indo-Aegean (IAeg) and Altaic-Gilyak (AG) must have remained particularly close after diffusion of the Proto-Steppe community because I can think of at least two sure features that they share with each other that couldn't have been inherited from the parent language. One is the wholesale softening of word-final *-t to *-s as seen in the changes on animate plural marker *-it (n.b. further erosion of word-final *-s causes in turn Proto-Altaic *-r₂) and the other is an occasional correspondence of *a in IAeg and AG with Boreal *u in certain key words. I attribute this curious development to an original mid-central schwa *ə which could sit equally in accented positions as well as unaccented ones.

Upon revisiting these ideas, I've just realized an interesting minimal triplet in Proto-Steppe that serves as a simple but effective argument to justify the necessity of at least four reconstructed vowels at this stage:

• *ta 'from'
• *tu 'you (sg.)'
• *tə 'that (near you)'

The first becomes the source of the Indo-European ablative *-ód and Uralic partitive *-ta. The PIE form originated by agglutinating the postposition to the nominal stem in IAeg (thus *-ata), followed by Penultimate Accent Shift in Old IE which took the fixed accent off the initial (*-áta), then Syncope (*-ád̰) and finally Vowel Shift, yielding PIE *-ód with regular rules. The second and last examples show a vital difference between them since *tu becomes *tʷa (> PIE *twe, n.b. vocalism secondarily affected by *me < Proto-Steppe *mi 'I') while *tə becomes IAeg *ta without labialization of the preceding stop (>PIE *to-). This is explained if there was an unrounded vowel distinct from both low central unrounded *a and high back rounded *u, namely the mid central unrounded schwa which fits so nicely into an otherwise common 3-vowel system. Forms that suggest to some long-range linguists the apparent existence of a proximal demonstrative **ti on the Proto-Steppe level^[1] are, I figure, caused by later analogical derivation out of inherited *tə since this proximal demonstrative is only evidenced in Boreal and AG while IAeg seems to preserve only *ta 'that' (> PIE *to- and Aegean *ta) with a distinct proximal counterpart *ka (> PIE *ḱo- and Aegean *ka). I take the IAeg evidence to show an original word *ka 'this' in Proto-Steppe since, if this is not so, the source of the IAeg form would remain much more obscure than that of Boreal and AG's *ti vis-a-vis the securely inherited deictic *tə. The Altaic forms with word-initial sibilant in place of expected *t- are surely caused by pre-Altaic palatalization before high front vowels as has also apparently occurred in its second person pronominal forms.

All these speculative ideas while interesting and worthy of discussion are however, of course, subject to some range of interpretation. Debate remains open.

Back to business: emphatic particles and verbal extensions

Now, returning to the safer topic of comparative linguistics, I still am trying to account for how my new solution concerning the prehistoric genesis of Proto-Indo-European's uvular sounds helps (or maybe hinders?) my attempts at trying to figure out the origins of the emphatic particle *[ǵ/g](ʰ)[e/o] which is thus far so hideously reconstructed by current Indo-Europeanists.

However, if we take the velar contained in the nominative first person singular pronoun, which appears to contain the fossilized remnants of the earliest form of the emphatic particle when the pronoun was first coined in the Late Period (ie. *h₁eǵoh₂, literally "(as for) my being here" from *h₁e "here" + *ǵe [emphatic] + *-oh₂ [old 1ps subjunctive]; parallel in development to the 1ps pronouns of Inuktitut uva-ŋa, Aleut ti-ŋ, and Proto-Semitic *an-āku), we are pointed to *ǵe as the most appropriate reconstruction. Any other forms of this particle would then have developed later after presumably being influenced by or merging with other existing words or particles with similar phonetics and meaning. In the earlier Mid IE (MIE) stage, we could then posit an emphatic particle *g̰a derived from Indo-Aegean *k’ə. From there, if comparable to Uralic emphatic *-ka attached to some pronominal stems^[1], we might finally reconstruct a Proto-Steppe emphatic particle *k’ə to account for both the Indo-European and Uralic forms. Can you all swallow that? Granted, this all remains tentative for now, but it's worth a shot.

Considering the differing velar stop in the emphatic particle, the verbal extension with uvular stop, seen in PIE verbs like *yeu-g- "to join" whose *g-less counterpart has identical semantics, must not be related afterall as I had previously assumed. Instead I'd like to suggest that it derives from a Mid IE aspectual marker *-ɢ̰a-, which originally might have conveyed a perfective sense. This implies earlier Indo-Aegean *-k’a- (thus Etruscan -ac- [perfective] as in tur-ac-e "was given") and relatable then to the Uralic perfective in *-ka. In this case, a Proto-Steppe perfective suffix *-k’a would be in order to explain the later forms.

That so far is my solution concerning that. Let's see if this idea sticks.
