The formation is similar to δάκτυλος (dáktulos) and κόνδυλος (kóndulos), probably first from a noun *σφόνδος (*sphóndos). Sometimes connected with words like σφενδόνη (sphendónē), σφεδανός (sphedanós) and σφαδάζω (sphadázō), but this is mere speculation. The variation σφ/σπ points to a Pre-Greek origin.
