What does eliminatory mean?
"Eliminatory" is a formal adjective describing something that eliminates — that is, removes, excludes, or expels. It appears most often in two domains. In physiology and medicine, it refers to the body's eliminatory processes or organs, such as the kidneys, lungs, and skin, which expel metabolic waste. In competitive contexts, particularly in British English, it describes the successive stages of a tournament that progressively knock out participants until a winner remains, as in an eliminatory round. The word derives from the Latin "eliminare," literally meaning to turn out of doors or beyond the threshold ("limen"), giving it a vivid underlying image of ejection. Because it sounds technical, "eliminatory" suits formal registers; everyday speech usually prefers simpler alternatives like "knockout" for competitions or "excretory" for bodily functions. It should not be confused with the related but distinct term "eliminative," common in philosophy.
adjectiveServing to or tending to eliminate; having the function of removing or expelling something, whether in competition, processes of selection, or bodily waste removal.
- Relating to or serving the elimination or expulsion of waste matter from the body (as in eliminatory functions of the kidneys and bowels).
- Serving to eliminate competitors or candidates, especially through successive stages of a competition.
"The tournament's eliminatory rounds whittled the field from sixty-four players down to just two finalists."
"The skin is one of the body's most important eliminatory organs, expelling waste through perspiration."
"Only eight teams survived the eliminatory phase of the championship."
Before it ever described knockout tournaments, "eliminatory" carried the literal sense of pushing something out the door — its Latin root means "to turn out of the threshold."

Etymology of eliminatory
"Eliminatory" comes from the Latin verb "eliminare," formed from the prefix "e-" (out) and "limen" (threshold), so the original image was literally driving someone out past the doorway. The verb passed into English in the mid-sixteenth century as "eliminate," first meaning to eject or banish, before acquiring its modern senses of removal and exclusion; the adjective "eliminatory" developed alongside it. The same root "limen" also gives English words such as "liminal" and "subliminal," both concerned with thresholds of perception.
