Steffi

Steffi is a German and Dutch diminutive of Stephanie, itself the feminine form of the Greek name Stephanos, meaning crown or wreath. The name gained particular international prominence through German tennis champion Steffi Graf, whose career in the 1980s and 1990s brought the pet form widespread recognition beyond German-speaking countries. Related forms include Steffie, Stefi, and the fuller name Stephanie, along with the masculine cognate Stefan.
