EtymologyEdit

From Proto-Slavic *sǫ-. Cognate with Old Church Slavonic сѫ- (sǫ-). From either Proto-Indo-European *sm̥- (one, same) or Proto-Indo-European *ḱom (with). Further cognate with Old Prussian san-, sen, Lithuanian sán-, są́-, Latvian suo- (the latter three being nominal prefixes), along with Old Lithuanian sa-, sù-, Sanskrit सम् (sam), (sa), Avestan 𐬵𐬀𐬨-(ham-), 𐬵𐬀-(ha-), Ancient Greek ὁμοῦ (homoû, together with), ἅμα (háma, together with), ἁ- (ha-, with), Latin semel (once).

Etymologically identical to the verbal prefix с- (s-), from Proto-Slavic *sъ(n)-. The difference in development is because of the looser juncture between early Proto-Slavic verbs and preverbs: thus, preverbal *sun was subject to Slavic Auslautgesetze. A similar situation is found in modern German. Not to be confused with Proto-Slavic *sъ- (good), from Proto-Indo-European *h₁su-.

A similar or equivalent prefix appears in a few words in Old Church Slavonic as соу- (sou-), with no trace of a nasal vowel, e.g. соугоубь (sugubĭ, double), with the root of -гиба́ть (-gibátʹ, to bend); compare Russian сугу́бый (sugúbyj, strict, pure, (originally) double). Some linguists believe this to be a distinct suffix, while Vasmer sees (in this case at least) assimilation from earlier *sǫ-, as above.
