Pronunciation

  • IPA: /ˈhaɪn(d)saɪt/[1]

Etymology

It is a compound, from English hind + sight.[2][3][4] In the sense of understanding after the event it was probably formed as a humorous opposite of the older foresight.[2]

Earliest recorded meaning

The rear sight of a firearm (1806 in Etymonline; 1851 in Merriam-Webster Unabridged and the Historical Thesaurus).[2][5][6]

Semantic evolution

The figurative sense, seeing after the event what ought to have been done, is attested by 1862 in American English, in the proverb “If our foresight was as good as our hindsight, it would be an easy matter to get rich”.[2] Merriam-Webster dates it to 1866[7] and the Historical Thesaurus to 1883.[6] The gun sense survives in the American colloquial phrase knock the hindsight out of, to defeat or demolish completely.[3]
