Proto-Italic

Etymology

    Ultimately derived from the root *sekʷ- (to follow), though the exact evolution of the term is unclear.

    Sanskrit सखि (sakhi) and Proto-Iranian *háxā likely reflect a Proto-Indo-European oi-stem noun *sokʷh₂ṓy (follower), which may itself derive from a noun of the shape *sokʷ-h₂.[1] According to the linguist Anthony Yates, it is possible that that the term *sokʷh₂ṓy could have been thematicized into a form *sokʷyo-, with the loss of the laryngeal due to the effects of Pinault's Law.[2][3] It is possible that this thematicized term may have yielded both Proto-Germanic *sagjaz and Proto-Italic *sokjos.[4][5] De Vaan, however, suggests that it is not certain whether the Latin and Germanic forms are derived from the same *h₂-stem noun due to the absence of the laryngeal. Regardless, de Vaan still accepts the reconstruction *sokʷ(h₂)-i-o- as the immediate pre-form of the Latin term, though he suggests it cannot be conclusively determined whether it is an adjective meaning "following" or a noun meaning "companion."[6]
