Despite the fact that in the vast majority of the villages of Aspropotamos the inhabitants spoke the Vlach language, Kamnai was Greek-speaking, as were the neighboring villages of Drosochori and Athamania. Although it was once a Vlach-speaking, it abandoned the Vlach language at the instigation of Father Kosmas Aetolus, who passed through the area of Aspropotamos around 1777, as part of efforts for national awakening and cultivation of feelings of homogeneity and unanimity during the Turkish occupation.
Το 1858, πέρασε από το Καμνάι ο Γάλλος αρχαιολόγος, Λέων Εζέ, σύμφωνα με τον οποίο: In 1858, the French archaeologist, Leon Eze, passed through Kamnai, according to whom: "The inhabitants of Kamniai speak nothing but Greek. They say that they were Vlachs once, but a Saint, who had come to preach the word of Christ, unable to be understood, had blamed this Romanian idiom, which made them adopt the Greek language."
Κατά την επίσκεψή του στο χωριό, ο ίδιος περιγράφει «During his visit to the village, he describes: "We are welcomed for our lunch stop at the house of an old woman, who asks me if I want to eat trout. I do not understand at first what he wants to say, but I see that these are trout. Trout from Acheloos, what a gift for an archaeologist!"
It is believed that during the Ottoman occupation, Kamnai was the main village in the surrounding area.
