Ancient GreekEdit

Alternative formsEdit


Doubtful. Younger form of Homeric and Old Attic ξύν (xún), Mycenaean Greek 𐀓𐀱 (ku-su). These probably reflect Proto-Indo-European *som- < *sem- (one, together) contaminated with the of *ḱóm (beside, with) along with a conflation of their meanings. A derivation from *som- alone is impossible, since the *s- would be expected to give h- (aspiration); neither is the ks- explainable from *ḱóm alone. The -u- is in line with the Pre-Greek shift of PIE *o > u before resonants, as in μύλη (múlē) (Cowgill's law).[1]




σῠ́ν (sún) (governs the dative)

  1. beside, with
