'antizymotic' originates from New Latin/modern formation, specifically from the elements 'anti-' + 'zymotic' (the latter ultimately from Greek 'zymōtikos'), where 'anti-' meant 'against' and Greek root 'zymē' meant 'leaven, ferment'.

'antizymotic' changed from New Latin word 'antizymoticus' (derived from Greek 'zymōtikos') and entered English usage in the 19th century, producing the modern English word 'antizymotic'.

Initially, it meant 'against fermentation', but over time it evolved into its broader medical/public-health meaning of 'preventing zymosis or infectious disease'.
