What does adulterator mean?
An adulterator is a person who adulterates — who deliberately mixes inferior, cheaper, or harmful substances into a product, most often food, drink, or medicine, usually to increase profit or bulk. The word is formal and relatively rare in everyday conversation, but it appears frequently in legal, regulatory, and historical writing about food safety, where notorious adulterators have been prosecuted for everything from watering down milk to adding toxic dyes to sweets. By extension, it can describe anyone or anything that corrupts the purity of something valued, such as an 'adulterator of the language.' The term carries unmistakably negative connotations of greed, deceit, and disregard for public health. It derives from the Latin verb adulterare, 'to corrupt or pollute,' the same root behind 'adulteration' and, more distantly, 'adultery' — both originally conveying the idea of making something impure.

- A person who adulterates — who mixes inferior, cheaper, or harmful substances into something (especially food, drink, or drugs), typically for gain.

"The adulterator blended chalk dust into the flour to increase his profits."
"Inspectors traced the outbreak back to an adulterator who had diluted the olive oil with cheap seed oil."
"Critics denounced him as an adulterator of the English language, filling his prose with needless jargon."
Standard plural; used when referring to multiple offenders, as in reports on food-fraud prosecutions.
"Several adulterators were named in the commission's final report on milk fraud."
The same Latin root that gave us 'adultery' also gave us 'adulterator' — because to the Romans, corrupting wine with water and betraying a marriage were both forms of 'making impure.'

Etymology of adulterator
Adulterator comes from the Latin verb adulterare, meaning 'to corrupt, pollute, or falsify,' formed from adulter ('an adulterer') plus the frequentative suffix -are. The root itself combines ad- ('toward') with alter ('other'), literally suggesting a turning toward what is other or foreign — hence the mixing in of something alien. The word entered English through post-classical Latin forms used in legal contexts concerning falsified goods. Its cognates include 'adulteration,' 'adulterant,' and 'adultery,' all of which preserve the core notion of impurity introduced by improper mixture.
