Gretta

Gretta is an English given name functioning as a variant spelling of Greta, itself a short form of Margareta, the Scandinavian and German form of Margaret. Margaret derives ultimately from the Greek word margaritēs, meaning pearl, which in turn was borrowed from a Persian or Sanskrit source. The name gained widespread use across Europe through the veneration of Saint Margaret of Antioch and various medieval queens and noblewomen. Related forms include Greta, Margareta, Margret, and Grette.
