Tom
Meaning
short for Thomas, 'twin'
Famously borne by Tom Pidcock, the British Olympic mountain bike champion. Famously borne by Tom Hanks, the Oscar-winning actor.
The story
Tom is the oldest kind of nickname, short for Thomas, the Aramaic word for twin, and for centuries it stood in for the ordinary Englishman: Tom, Dick, and Harry. Mark Twain gave it a permanent boyhood in Tom Sawyer, and American parents long put the short form itself on the birth certificate, keeping Tom solidly in use through the middle of the twentieth century. Since then the standalone spelling has faded, with families choosing the full Thomas and saving Tom for the playground. Its most famous modern bearer needs little introduction: Tom Brady, the quarterback taken 199th in his draft class, who went on to win seven Super Bowls, more than any single franchise, let alone any other player. A short, sturdy, open-faced name that has never needed more than one syllable to do its work.
