Meaning & History
American actress Cameron Diaz and musician Benji Madden named their daughter, born in 2020, Raddix Madden. Cameron explained the name is an elaboration of the word "rad." Rad, a diminutive of radical was first an adjective, borrowed in the 14th century from the Late Latin radicalis, itself from Latin radic-, radix, meaning "root." And the earliest uses of radical are indeed all about literal roots, hinging on the meaning "of, relating to, or proceeding from a root."
