c.1200, from Anglo-Fr. lycoryc, from O.Fr. licorece, from L.L. liquiritia, alteration of L. glychyrrhiza, from Gk. glykyrrhiza, lit. "sweet root," from glykys "sweet" (see glucose) + rhiza "root;" form influenced in L. by liquere "become fluid," associated by the method
of extracting the sweet stuff from the root. Fr. réglisse, It. regolizia are the same word, with metathesis of -l- and -r-.
