Tommy
Meaning
diminutive of Thomas, from Aramaic Ta'oma, 'twin'
Famously borne by Tommy Caldwell, who made the first free ascent of El Capitan's Dawn Wall with Kevin Jorgeson.
The story
Tommy is Thomas at its friendliest, the ancient Aramaic name Ta'oma, meaning twin, worn down to something you could shout across a backyard. It has long stood on its own two feet: in Britain, Tommy became the affectionate name for the common soldier, the Tommies of the world wars, and in America plenty of boys were Tommy on the birth certificate itself, no Thomas behind it. That habit crested at midcentury, and the chart runs at its highest from the 1930s through the 1960s, the heyday of ballplayers and paperboys named Tommy. Since then it has settled rather than sunk, holding a steady middle level for half a century as most parents moved the full Thomas onto paper while keeping Tommy for the kitchen table. Easygoing and durable, it remains one of the most instantly likable names in the book.
