Thommas is an uncommon variant spelling of Thomas, which originates from the Aramaic word "t'oma", meaning "twin". This name has been widely used throughout history, particularly among Christian cultures due to its biblical associations. It was borne by several prominent historical figures, including early Church fathers and saints, further contributing to its popularity.
Thommas is quite rare as a given name for both sexes, with only two births recorded between 1956 and 1959.
