Thomasa
A girl's name of Aramaic origin with 304 recorded U.S. births.
Meaning & Origin
Thomasa is a three-syllable girl's name with a open, warm sound — a soft ending that crosses many language boundaries. With only 304 recorded U.S. births, it is exceptionally rare — the kind of name most people encounter for the first time when they meet your child.
Thomasa is not in the current top 1,000 girl names nationally, making it an uncommon choice — though your state or community may differ.
Thomasa is a girl's baby name of Aramaic origin, a feminine form of Thomas — from the Aramaic meaning 'twin.' Thomas the apostle, known as Doubting Thomas, is one of the most recognizable figures in the New Testament, whose request for physical proof of the Resurrection became a touchstone of human faith and doubt.
Thomasa carries the apostle's Aramaic heritage in a graceful feminine form. It belongs to the tradition of feminizing classic apostolic names — like Thomasina, Tomasa, and Tomisina — giving the twin-name's profound New Testament significance a softer, more personal expression.
