Here, and on the connected pages, are some very interesting Thracian
words and names.
The first that really jumped out at me was the suffix -suchis/-sykos/-
sokos, translated as "girl". This is similar to the Etruscan "sech",
meaning "daughter". Noting that, with the recent article on apparent
Anatolian DNA connections in Tuscany, it seems not improbable that
the Etruscans were on the Eastern Aegean, where they could easily
have picked up such words - especially if the Egyptian descriptions
of the Sea Peoples are correct in naming the Etruscans as one of
them, which would mean that the Etruscans would have had experience
in trading - a fine way to ammass foreign words.
The next was this entry:
"Achelo:os, Achelo:n (Leo Gramm., Georg. Amartol., Georg. Mon.; AD
917) - small river near the town of Anchialo (Pomorie) on the Black
Sea. The name is explained from the IE *&kWel- `water', preserved in
the Lith. hydronym Akkele (lake). It is also compared with the Lydian
river name of Achéles, Akéles, the Phrygian akala `water'. As
identical are given also the name of Achelo:os of five rivers in
Greece. The same Thracian name is hidden in the name of the small
Black Sea town of Anchialo, attested by Strabo under the form of
Anchiále: and by Apian as Anchíalos, which is in fact a Grecized form
of the Thracian name, linked with the Greek word anchíalos `coastal'."
The Lydian river name is highly reminiscent of Achileus, i.e. "he of
Akéles?"
Another is this:
Harmonia (Hierokl., Synekd.) - village to the east of the middle
course of Vardar. It is supposed Harmonia is a Grecized form of some
Thracian name - *-Armonia or *Armania (compare the village name of
Germanía, formed from a river name with the suffix -i). As such it
can be compared with the Lith. river name Armona, Armenà, from the
Lith. armuõ, -eñs `a swamp, bog', arma `the same'; for more related
names see above under *Armula.
Alternately, this and the town of Germania could have been Germanic
towns that were invaded by Thracians. Alternately, it could be a
Hellenized version of Sarm{o/a}nia. Could there be - as the Thracians
did have names based on animals, like Hellenized "Odrysai" from *udr-
{u/o}s-oi "of the otter" and Bébrykes (related to PIE
*bhebhrus "beaver" - possible commections to West-Central IE *k^ormo-
"ermine"?
