σύν (Ancient Greek)
Where does "σύν" come from?
Ancient Greek σύν “with, beside” is a younger reshaping of an older form ξύν, already found in Mycenaean Greek as ku-su (*ksun), and is usually traced back to Proto‑Hellenic *ksún. Its deeper origin is uncertain: it may reflect a blend of Proto‑Indo‑European *som- “one, together (with)” with influence from *ḱóm “beside, with,” which could explain the meaning but leaves the unexpected vowel -u- hard to account for. Because of these sound difficulties, its exact tie to forms like Lithuanian sù and Proto‑Slavic *sъ(n) is debated, even if they may ultimately be related through the same “with/together” idea.
