Thomas

Traditionally explained as “twin.”

Thomas is a classic masculine given name used across many languages and countries. In Christian tradition, it’s associated with the apostle Thomas, which helped make it durable and widely recognized over centuries. Etymologically, Thomas comes from an Aramaic name commonly glossed as “twin,” and it spread broadly through Greek and Latin forms into later European usage. Because it has been used for so long and in so many places, you’ll see small spelling and pronunciation differences by language, even when the written form stays the same. In English, pronunciation is often TAH-muhs (two syllables), though some regions prefer a slightly different vowel. It’s also very nickname-friendly, with familiar shortenings like Tom and Tommy that remain recognizable on their own.

Etymology: From an Aramaic name commonly glossed as “twin,” transmitted through Greek and Latin into widespread Christian-era use.
