bywyd

From Proto-Brythonic *bïwïd, from Proto-Celtic *biwotūts (compare Old Irish bethu, bethad, Irish beatha), probably from a derivative of Proto-Indo-European *gʷih₃wo-teh₂ (compare Latin vīta, Ancient Greek βίοτος (bíotos), Old Church Slavonic, животъ (životŭ, “life”), Lithuanian gyvatà (“life”), Sanskrit जीवित (jīvitá), Avestan gayo (accusative ǰyātum) "life")), ultimately from *gʷeih₃w- (“to live”), compare *gʷih₃wós (“alive”).
