Thomassia

English, feminine variation of Thomas

Thomassia Origin and Meaning

The name Thomassia is a girl's name of French origin.

Thomassia is a feminine form of Thomas, which derives from the Aramaic name Ta'oma meaning 'twin.' While Thomas has been a perennially popular masculine name throughout Christian cultures, Thomassia represents a rare feminization that adds elegance through its extended ending. The '-ia' suffix follows the pattern of creating feminine variants seen in names like Alexandra or Victoria. Thomassia has never ranked among common girls' names in the United States or other English-speaking countries, making it an exceptionally distinctive choice. Despite its rarity, it maintains connection to the familiar and respected Thomas tradition while offering a pathway to the friendly nickname Thoma or more common Thomasina variants. The name carries a scholarly, slightly formal impression.
