Meaning & Origin
Tadd is a boy's baby name of Welsh origin, a variant of Tad, from the Welsh word tad meaning 'father' — or as a short form of Thaddeus, from the Aramaic meaning 'heart' or 'courageous.'
Tadd has a crisp, one-syllable punch that feels both familiar and rare. The double-d spelling gives it a slightly more distinctive look than the simple Tad, and as a short form of Thaddeus, it connects to the biblical apostle with that name.
