kauṃ

Etymology
From (whence 🇨🇬), from there uncertain. Likely borrowed from a language (obviously into ), from. Compare 🇨🇬, 🇨🇬, both meaning "sun" and "day" (Meilet 1914:19). While Windekens (1941) suggested a borrowing from Tocharian into Turkic, Pedersen (1944:11) was in favor of a necessarily opposite borrowing from Turkic into Tocharian. This was later acknowledged by Windekens (1976:627). This theory is also supported by combinations of the meanings "sun" and "day" being very unusual in the Indo-European languages.

Winter suggests a connection with 🇨🇬, however this root is isolated in Indo-European and further unlikely compared to the evidence for the former theory.
