Eliminate, Exterminate & Eradicate

Eliminate (pronounced ih-lim-uh-neyt)

(1) To remove or get rid of, especially as being in some way undesirable.

(2) To omit, especially as being unimportant or irrelevant; leave out.

(3) To remove from further consideration or competition, especially by defeating in sport or other competitive contest.

(6) In mathematics, to remove (a quantity) from an equation by elimination.

(7) In sport, as elimination & eliminator (drag racing): category classifications. 

1560–70: From the Latin ēlīminātus (thrust out of the doors; expel), past participle of ēlīmināre, the construct being ē- (out) + līmin- (stem of līmen (threshold)) + -ātus (the Latin first/second-declension suffix (feminine -āta, neuter -ātum)).  The most commonly used form in Latin appears to have been ex limine (off the threshold).  Used literally at first, the sense of "exclude" was first attested in 1714; the now obsolete sense of "expel waste from the body" emerged circa 1795 although the general sense of an "expulsion of waste matter" is from 1855.  Eliminate is a verb, if used with an object, the verbs are eliminated & eliminating, eliminability, eliminant & eliminability are nouns and eliminable, eliminative and eliminatory are adjectives.

Exterminate (pronounced ik-stur-muh-neyt)

Totally to destroy (living things, especially pests or vermin); annihilate; extirpate.

1535–1545: From the Latin exterminātus, past participle of extermināre (to drive away (from terminus boundary)), perfect passive participle of exterminō, the construct being ex- + terminō (I finish, close, end), from terminus (limit, end).  In Late Latin there was also the sense "destroy" from the phrase ex termine (beyond the boundary), ablative of termen (boundary, limit, end).  The meaning "utterly to destroy" appeared in English only by the 1640s, a sense found earlier in equivalent words in French and in the Vulgate; earlier in this sense was the mid-fifteenth century extermine.  Exterminator actually came earlier: as early as circa 1400, the Late Latin exterminator (from past participle stem of exterminare) had the sense of "an angel who expells (people from a country) and, by 1848, as a “substance for ridding a place of rats etc) and by 1938 this was applied to a person whose job it was.  Exterminate is a verb, used with an object the verbs are exterminated & exterminating, exterminable, exterminative & exterminatory are adjectives and extermination & exterminator are nouns.

Eradicate (pronounced ih-rad-i-keyt)

(1) To remove or destroy utterly; extirpate.

(2) To erase by rubbing or by means of a chemical solvent or other agent.

(3) Of plants, to pull up by the roots.

1555–1565: From the Latin ērādīcātus (usually translated as “destroy utterly”; literally “pull up by the roots”), past participle of ērādīcāre (root out, extirpate, annihilate), the construct being ē- (out) + rādīc- (stem of rādīx (root) (genitive radicis)) + -ātus (the Latin first/second-declension suffix (feminine -āta, neuter -ātum)).  The assimilated form of ērādīcāre is derived from the primitive Indo-European wrād (branch, root) and from the same source, the native form of the same idea existed in mid-fifteenth century Middle English as outrōten (to root (something) out; eradicate).  A surprisingly recent creation in 1794 was ineradicable and within a few years, ineradicably.  Eradicate is a verb, eradicant is an adjective and noun, eradicated & eradicating are verbs (used with object), eradicable & eradicative are adjectives, eradicably is an adverb, eradication & eradicator are nouns.

Eliminate, exterminate and eradicate in the age of pandemics

In Modern English usage, eliminate, exterminate and eradicate are often used interchangeably despite differences in nuance.  This means also the wealth of synonyms the three enjoy are sometimes haphazardly used although some overlap does exist, the synonyms including: annihilate, expunge, abolish, erase, uproot, extinguish, efface, demolish, total, abate, liquidate, obliterate, trash, squash, purge, extirpate, scratch, slaughter, decimate, execute, massacre, abolish, erase, extirpate, destroy, oust, waive, ignore, defeat, cancel, exclude, disqualify, invalidate, drop, eject, expel, liquidate, omit, terminate, slay, discard & disregard.

In the (relatively) happy times before the emergence of SARS-Cov2's Delta variant, the New Zealand prime minister declared COVID-19 “eradicated but not eliminated” which did sound given that, regarding disease, the words have specific, technical meanings.  In the context of disease, eradication refers to the complete and permanent worldwide reduction to zero new cases through deliberate effort.  Elimination refers to the reduction to zero (or a very low defined target rate) of new cases in a defined geographical area, which can be any size, a province, country, continent or hemisphere.  As used by virologists and epidemiologists therefore, eradication is used in its normal conversational sense but elimination is applied with a specific technical meaning.  There is a quirk to this. The World Health Organization (WHO) certified the global eradication of smallpox in 1980 although small cultures remain in US and Russian research laboratories.  If these residual stocks are ever destroyed, the WHO may adopt some new term to distinguish between eradication in the wild and an absolute extermination from the planet.  Nobody seems now to believe COVID-19 will ever be eliminated, exterminated or eradicated.  It seems here to stay.

Defendants in the dock, International Military Tribunal (IMT, the main Nuremberg trial (1945-1946)). 

The meanings of eliminate, exterminate & eradicate, both in their English senses and in translation from German have been debated before.  Although not defined in law until the 1948 Convention on the Prevention and Punishment of the Crime of Genocide (CPPCG), the newly (1944) created word genocide appeared in the indictments served at the main Nuremberg trial (1945-1946) upon those accused under count IV, crimes against humanity.  This attracted the interest of lawyers who noted the words exterminate and eliminate appear both in the academic and legal discussions about the novel concept of genocide and in translations of many documents from the Third Reich which related to the Jews.  Defense counsel probed what was meant by these words and whether, in original or translation, their actual meaning in the context of their use was in accord with what was meant when applied to genocide.  The etymological excursion didn’t much help the defendants, most of whom were hanged.  Hermann Göring also raised an objection to a translation from the German being rendered as "final solution to the Jewish problem" rather than "total solution" which, he argued, should compel the court to draw a different inference.  In both discussions, the judges concluded what was being discussed was mass-murder and the relative degree of applicability between synonyms was not a substantive point.

Professionals in the field of pest control actually stick more closely to classic etymology in their technical distinction between the two central words: extermination and eradication.  Extermination (from the Latin, exterminare meaning “out of the boundary” and related to the deity Terminus who presided over boundaries) means to drive the pests beyond the boundaries of the building.  It doesn’t of necessity mean the pests are all dead, just that they are no longer in the building.  Eradicate (from the Latin eradicare meaning to root out) refers to the processes leading to extermination, to bring to light the breeding spots, the places where the infestation has, so to speak, taken root.
