köken: From Middle High German vletschen (“bare one's teeth”), from or related to vletzen (“flatten, spread out”) (for the change of -tz- to -tsch, compare rutschen), related to Old High German flaz and English flat.
Fletsche deine gefräßigen Zähne mir nicht so entgegen! Mir ekelt’s!
Du fletschest mich lieblich an mit weissen Zähnlein, deine bösen Augen springen gegen mich aus lockichtem Mähnlein!
köken: From imbrogliare (“to tangle”), cognate with and probably from an earlier form of French embrouiller (“muddle, embroil”), from em- (“en-”) + brouiller.
köken: From the bony- stem of the verb bonyolít (“to complicate”) + -odalom (noun-forming suffix). Created during the Hungarian language reform, which took place in the 18th–19th centuries.
