Temematic

Last year I caught wind of something called "Temematic". This was a language somewhere in the hazy region between Old Prussian, German, and Celtic that was not any of the above. Then the Slavs came and the place enters actual history after all the damage had been done. Alexei Kassian is now on Temematic's case.

Holzer in 1989 had defined "Temematic" from the shift of obstruents: tenues > mediae, mediae aspiratae > tenues. Overall IE *p *t *k > bdg, IE *bʰ *dʰ *gʰ > ptk, but IE (*b)*d *g were retained intact as bdg. That shift did not apply to the Balto-Slavic mainline; only to 45 words he'd found within Balto-Slavic. These then would be loans. Maybe it happened in Pomerania.

Most scholars shrugged and went along, it seems, until Matasović in 2013. This one could not find any substrate loans in Balto-Slavic; which - however annoying for Holzer - turns out a boon for students of Indo-European who can now work with Balto-Slavic as a pure offshoot from the baseline of (no less than) Indo-Iranian.

Kassian revives the Temematic hypothesis by allowing for 17 of its words which he can, still, find in protoSlavic. Baltic as well, but independently.

Kassian is elsewhere something of a dissident in Slavic linguistics since he'd date the Slavic breakup to the early first millennium AD, as against the consensus who date it to the middle. But that isn't important here.

What matters here is that Kassian sees the protoSlavs - the first unified Slavs - leaving the Baltic Heimat sometime 1500-1000 BC. They then met up with total strangers. For these 17 words, those indigenes were the Temematic people.

Kassian's Temematic-speakers moreover were not even IndoEuropean. So this looks like a different signal more than a refinement of the signal. They'd be West European Substrates, usually associated with the Neolithic farmers who preceded all those other "Sons of Aryas". Most today associate them with the Funnel-Beaker peoples. Some of their other words entered Greek.

Also: the mix happened in two pulses. One was just the Funnel-Beaker substrate. The later pulse was the pulse we can (still) honestly call Temematic, having undergone the sound-shift; this happened in the first millennium BC or theoretically somewhat later.
