Meaning & origin
Thomasa is a distinctly rare feminine form of Thomas, first recorded in U.S. data in 1921. Its peak year was 1963, yet even then it never approached common usage, with fewer than five births annually and a one-in-N occurrence too low to calculate. The name's trajectory has been stable, meaning it persists at the same very low level decade after decade without signs of revival. Most of its use occurred in the 1960s, but it never appeared in any state's top 1000 names. For parents seeking an obscure, historically grounded name with a clear meaning, Thomasa offers a connection to the ancient Aramaic word for 'twin', but its rarity means it will likely remain a unique choice.
Thomasa is the feminine form of Thomas, derived from the Aramaic word 'te'oma' meaning 'twin'. The name came into use via Greek (Thomas) and Latin, with feminine variants appearing in various European languages. It has been used sporadically in English-speaking countries since the 19th century, but never achieved widespread popularity.
