What does eliminator mean?
An eliminator is someone or something that removes, rules out, or gets rid of another thing. The word functions both as a general agent noun — an air purifier can be described as an allergen eliminator, for instance — and in a more specific sporting sense, where an eliminator is a round, heat, or fixture from which the losing competitor or team is knocked out of a tournament. In this competitive usage, often found in phrases such as 'title eliminator' in boxing or racing, stakes are inherently high because defeat ends a participant's chances outright. The term derives ultimately from the Latin eliminare, meaning to turn out of doors or expel, which itself traces back to limen, meaning threshold; the underlying image of putting something outside the door remains vivid in modern use. The word carries a neutral to slightly forceful connotation, suggesting decisiveness and finality rather than cruelty, and it appears frequently in sports reporting, consumer product names, and technical writing.
A person or thing that eliminates or removes something.
"This device acts as an effective pest eliminator for the garden."
Often used attributively or in product names, giving a commercial flavour.
A round or match in a competition in which the loser is knocked out.
"The two fighters meet again in a title eliminator next month."
Regular plural; used when referring to multiple removal devices or several knockout matches.
"The tournament features two eliminators before the semi-finals."
Before it meant knockout rounds, 'eliminator' came from Latin limen — the threshold — so every eliminator literally sends someone out past the doorway.

Etymology of eliminator
Eliminator was formed in English from the verb eliminate plus the agentive suffix -or, first appearing in the early nineteenth century as the verb itself became common. Eliminate comes from Latin eliminare, 'to turn out of doors, banish', formed from e- ('out') and limen ('threshold'). Cognates sharing the same root include limit and limitation, which likewise descend from limen via Latin limes.
