The etymology of the word KOZAK.
For objective reasons, historically, the kozaks settled on the border territories, where the history of kozacks has absorbed a lot of Turkic-speaking and not only borrowings. Which allows me to make assumptions that the word KOZAK comes from the Turkic words Koz — eye (to see) and AK — white (light) its meaning seeing light or clairvoyant. Shalom KOZAKs))))
