Etymology
The origin is.

Benveniste connected with 🇨🇬 and 🇨🇬, assuming a basic heteroclitic r/n-stem, where Armenian would have generalized the n-stem variant, according to Olsen, "probably,  →  on the basis of the locative singular, evidently an important case form in a word of this meaning". According to Kroonen, if the appurtenance of Armenian is accepted, the ablauting heteroclitic can be reconstructed as nominative, genitive.

The above etymology is rejected by Pokorny and Beekes on phonetic grounds: the sound change of 🇨🇬 → 🇨🇬 is irregular. Beekes remarks that we may be dealing with a word.
