Meaning and origin of Thomas
Thomas is an Aramaic and Greek name that means “twin”.
Thomas comes from the Aramaic te'oma, "twin". In the New Testament, Thomas is the apostle who doubts the resurrection until he sees the wounds of Jesus, which gave English the phrase "doubting Thomas". Saint Thomas Becket, the archbishop of Canterbury murdered in his cathedral in 1170, made the name enormously popular in medieval England, and Thomas Aquinas became one of the great medieval theologians. Americans know it through Thomas Jefferson and Thomas Edison. The name feels classic and dependable. Tom and Tommy are nicknames, and Tomás, Tomasz and Tommaso are forms used elsewhere.
