deterrence

Etymology

The OED takes it as formed from English deterrent + -ence;^[2] Dictionary.com also derives it from the adjective,^[3] while Merriam-Webster Unabridged and Webster's Third form it from deter.^[4][5] The adjective is recorded from 1829, in Bentham, from Latin dēterrēns, the present participle of dēterreō (“to frighten from, discourage from”),^[6][2] formed from dē- (“away”) and terreō (“to frighten”).^[6]

Earliest recorded meaning

Deterring, or preventing something by fear: 1861, in T. B. L. Baker, collected in War with Crime (1889).^[2] Merriam-Webster gives the same year,^[4][7] and Dictionary.com 1860–65.^[3] Etymonline, however, dates the noun to 1788, for the act of deterring and that which deters.^[6]

Semantic evolution

The word was first used of discouraging crime by the fear of punishment, a sense Merriam-Webster still lists first.^[4][7] In the Cold War it came to mean the prevention of war by the threat that nuclear weapons would be used against an aggressor;^[2] Etymonline dates this use to 1955, as the strategy of showing the will to inflict punishing damage so that an enemy would refrain from acting, and notes that the idea of assured destruction grew out of it.^[6] Deterrent had been applied to nuclear weapons from 1954.^[6]
