Flint

Flint is an English word and surname used as a given name. It names the hard stone historically used for tools and for striking sparks. As a surname, it could connect a family with flinty ground; as a modern first name, it can simply refer to the material itself. That gives it both a landscape history and a direct nature-name meaning.

The name also has a varied fictional life. Captain Flint appears in the background of Treasure Island, while inventor Flint Lockwood belongs to Cloudy with a Chance of Meatballs. Those associations offer adventure or inventiveness without defining the personality of a real child. Its single syllable and clear spelling make it compact, and Flynt is an alternative for families who prefer a different written form.
