What does extermination mean?
Extermination is a noun denoting the complete destruction or killing of a group of living beings — whether people, animals, or pests — or the thorough elimination of something unwanted. The word carries grave connotations when applied to humans: it is central to discussions of genocide and appears in historical phrases such as 'extermination camps,' referring to facilities where millions were murdered during the Holocaust. In more mundane contexts, particularly North American English, extermination refers routinely to pest control — ridding homes of termites, rats, cockroaches, or other vermin. Derived from the Latin verb exterminare, which originally meant to drive out or banish beyond one's boundaries, the word has shifted over centuries from expulsion to outright destruction. Its derivatives include exterminate (verb) and exterminator (one who carries out the act). Because of its severity, writers typically reserve it for situations involving totality and intent rather than partial or accidental loss.
The act of completely destroying or killing a group of people, animals, or things.
"Historians documented the extermination of entire villages during the conflict."
When applied to humans, the term is heavily associated with genocide and mass atrocity.
The professional elimination of pests such as insects or rodents from a building or area.
"The restaurant closed temporarily for fumigation and pest extermination."
This sense is especially common in American English and is considered routine rather than alarming.
The plural is rare because the concept is usually treated as uncountable; it appears mainly when referring to multiple distinct instances or events.
"The report catalogued numerous exterminations carried out during the war."
The word extermination comes from Latin roots meaning 'to drive out beyond the boundaries' — originally about banishing, not killing.

Etymology of extermination
Extermination derives from the Latin verb exterminare, formed from ex- ('out of') and terminus ('boundary'), originally meaning to drive out or banish beyond the limits of a territory. The word entered English in the early 17th century, initially retaining this sense of expulsion before evolving to signify complete destruction or killing. It shares its Latin root with related words such as terminate, determine, and terminal, all stemming from terminus, meaning boundary or limit.
