Tom

Tom is an English short form of Thomas, itself derived from the Aramaic name Toma, meaning twin. The name entered European use through the apostle Thomas in the New Testament, one of the twelve disciples of Jesus, and became widely popular across medieval Christendom. Its casual, familiar quality made Tom a common everyman name in English culture, reflected in expressions like Tom, Dick, and Harry. Related forms include Tomás, Tommaso, Tomas, and Tomasz across various European languages.
