Meaning & Origin
a village in Creaca, Sălaj County, Romania
Jac is a boy's baby name, a Welsh short form of Jacob or Jack, from Hebrew Ya'akov meaning 'supplanter' or 'heel-holder.' In Welsh, Jac is the natural Cymric form of Jack, and Welsh-speakers have used it for centuries as the everyday form of the name in Wales. It carries both the ancient Hebrew meaning and the quintessentially Welsh identity.
Jac is the kind of name that carries enormous heritage in minimalist packaging — three letters, one syllable, and the full weight of Welsh cultural identity alongside one of the most beloved names in the English language.
