fæþm m (nominative plural fæþmas)
From Proto-Germanic *faþmaz, from Proto-Indo-European *peth₂-. Cognate with Old Saxon faþmos; Dutch vadem, vaam; Old High German fadum (German Faden), Old Norse faðmr (Icelandic faðmur, Danish favn, Swedish famn). The Proto-Indo-European root is also the source of Ancient Greek πετάννυμι (petánnumi) and Latin pateō.
