Aonghas

Irish

From Middle Irish Aengus, Oengus, from Old Irish Oíngus,^[1] from oín (“one”), from Proto-Celtic *oinos, from Proto-Indo-European *óynos (“single, one”). The etymology of the second element is disputed; most likely it is gus (“strength, vigour”), from Proto-Celtic *gustus, or it may be from Proto-Indo-European *ǵews- (“choose”).
