From eitherProto-Indo-European*sm̥-(“one,same”) in which case inherited fromProto-Balto-Slavic*san and cognate withLatviansa-,Lithuaniansu, or fromProto-Indo-European*ḱom(“with”).[1][2]
Etymologically identical to the nominal prefix*sǫ-. The difference in development is because of the looser juncture between early Proto-Slavic verbs and preverbs: thus, preverbal*sun was subject to SlavicAuslautgesetze. A similar situation is found in modern German. Not to be confused with*sъ-(“good”), from Proto-Indo-European*h₁su-.
*sъ(n)
Because of the law of open syllables, the final*-n was normally dropped. But when combined with a stem that originally began with/j/, it was attached to the following word. Cf. Russianею(jeju), butс(s)нею(neju) (*sъnjejǫ >/snˈeju/) etc.
