An Etymological Dictionary of the German Language/Annotated/Quendel
Quendel, masculine, ‘wild thyme,’ from the equivalent Middle High German quëndel, most frequently quënel (konel), Old High German quënala (chonala), feminine; compare Dutch kwendel, Anglo-Saxon cunele. It is hardly probable that this is an early loan-word from Latin conîla (Greek κονίλη), ‘thyme,’ since the Romance languages have not preserved the word.
