Etymology

From Hittite [script needed] ‎(suppi, “clean”). Most likely a Proto-Kartvelian borrowing during the late, Proto-Karto-Zan stage of development (XIX-VIII centuries BC).(Can this⁽⁺⁾ etymology be sourced?)

On the other hand, according to Ačaṙean, a borrowing from Iranian from a word in the family of Persian سفید ‎(safid, “white”).
