i've asked a friend of mine from trabzon. this is what he says:
Büyük ihtimalle Rumca kaynaklı
Hopa civarında kullanılan lazcayada benziyor
Bence Artvin lazcası
most likely anatolian greek
it seems lazca (the laz language) spoken around hopa
in my opinion it's lazca of artvin
i've just listened to
this song. i feel my friend is right.
by the way, i've had been unaware of kazım koyuncu until the day i heard his death on the tv.
may he rest in peace.
