Would you consider making the word "petit" common, GAGL? Even though, technically, it is a "foreign" word, it's so much used in the public, one may not notice!
There is a class of crimes defined as "petit" and here, courts and juries are also called "petit", so perhaps it is more common than rare. Esp. given how many "petty" crimes are committed around the world, and thereby, "petit" courts and juries are employed to resolve them.
