An Etymological Dictionary of the German Language/Annotated/Latwerge
Latwerge, ‘electuary, confection,’ from the equivalent Middle High German latwërge, laiwêrje, latwârje, feminine; the t as in Lattich represents ct (assimilated tt); lactuárium has a in the unaccented first syllable for e, as in Lafritze. This foreign term is based on the equivalent Middle Latin electuarium, which sometimes in Middle High German preserves its primary form, electuârje, lectquerje. The Middle Latin word, which originated in Greek ἐκλεικτόν, ἔκλειγμα, ‘medicine that dissolves in the mouth,’ belongs to the medical art of the Middle Ages, which was learned from the Greeks (compare also Lafrige, Büchse, Arzt, &c.), and was introduced into German through a Romance medium — Italian lattovaro, French électuaire (whence English electuary).
