What does eradicator mean?
An eradicator is a person or, more commonly, a thing that eliminates something completely and permanently — a disease, a pest, a weed, or another stubborn problem. The noun derives from the verb eradicate, which itself comes from the Latin radix, meaning 'root,' so the word literally suggests tearing a problem out by its roots rather than merely suppressing it. In modern usage, eradicator appears most often in technical and commercial contexts: herbicides marketed as weed eradicators, insecticides described as pest eradicators, and cleaning products billed as stain eradicators. It can also be applied figuratively and formally to people or programs that wipe out social ills, though such uses are less frequent. The word carries connotations of thoroughness and finality; an eradicator does not reduce or control but removes entirely. Its strength makes it a favorite of advertisers and public-health writers alike, both of whom want to convey total victory over whatever nuisance they describe.

Etymology of eradicator
Eradicator comes from the Latin verb eradicare, formed from e- ('out') and radix ('root'), meaning 'to pull up by the roots.' English borrowed eradicate in the early 17th century, and the agent noun eradicator followed as a natural derivation, denoting one who or that which eradicates. The same Latin root radix gives English several other words, including radical, radish, and radicle.
