The last Spot the Language piece was solved by a Turkish commenter who is one-half the ethnicity of the language: the Laz people. Here is his comment about the Laz and the region where they reside. Very nice comment and I would like to thank the commenter very much.
Ertuğrul Bilal: I am a Turco-Laz half-breed. There are at least half to close to one million people like me. I identify as a son of the homeland and as any particular ethnicity. This is also the primal identity adopted by almost all Lazes, who see themselves ethnically Laz only secondarily. Let’s put it his way: Black Sea people’s loyalty is more territorial than ethnic, just like cats.
FYI: Laz is not related to Turkish or any other Turkic language. It is part of the Kartvelian linguistic family, consisting of Georgian, Svan, and the Mingrelian-Laz twin peoples. The single substantial difference between the last two being that Mingrelians remained Orthodox, while Laz converted to Islam in late 15th and 16th century; otherwise the discrepancy is solely dialectal.
Laz people live on Northeastern Black Sea coast, actually at the eastern end towards the Turkish-Georgian frontier. This region has always been multi-cultural just as Anatolia used to be, only somewhat more so; even if superficially it is less obvious nowadays.
The local populace was originally mainly Tzans, a rather obscure culture, apparently resulting from an amalgamation of indigenous populace with immigrating/invading Cimmerians, westward-advancing Kartvelians and perhaps some other not well-known tribes ancestral to both Mingrelians and Laz in Antiquity when Greek colonizers founded practically all cities and most of the towns.
Today, you may find Turks (Alevi Turcomans forcibly relocated there by the Ottoman empire in 16th century who converted to Sunnism, except for a few thousand who remained Alevi) and other people of Turkic origin like my late father who told me his paternal lineage emigrated from Northern Dagestan and was either Nogay or Kumyk.
In addition, there are now Lazes, Georgians, Armenians (Hemshinids Islamicized long ago and some others forcibly assimilated to Turks in 1915), and Islamized Greeks, to mention only the most numerous.
Let’s put it this way – we are accustomed to quite a wide diversity of ethnicities in our country and especially in my parents’ native region, even if the official doctrine still tends to disregard the fact, and while it is not outright denial as in the past, a more subtle denial yet exists.
