In modern use a derivative of Lynn, formed with the French feminine diminutive suffix -ette. However, this is not the origin for the name as used in Tennyson's Idylls of the King (1859–85), through which it first came to public attention. There, it represents an altered form of some Celtic original; compare Welsh Eluned.
German and Jewish (Ashkenazic): nickname for a big man, from Middle High German grōz ‘large’, ‘thick’, ‘corpulent’, German gross. The Jewish name has been Hebraicized as Gadol, from Hebrew gadol ‘large’. This name is widespread throughout central and eastern Europe, not only in German-speaking countries.
