type of leguminous plant, the dried roots of which were anciently used as a medicine and as a sweet, also liquorice, c. 1200, licoriz, from Anglo-French lycoryc, Old French licorece (also recolice), from Late Latin liquiritia, alteration of Latin glychyrrhiza, from Greek glykyrrhiza, literally "sweet root," from glykys "sweet" (see gluco-) + rhiza "root" (from PIE root *wrād- "branch, root"); form influenced in Latin by liquere "become fluid," because of the method of extracting the sweet stuff from the root.
