Pronunciation

  • UK: /ɪˈɹeɪz/[1]
  • US: /ɪˈɹeɪs/, /i-/[1]

Etymology

It is borrowed from Latin ērāsus, the past participle of ērādō (“to scrape out, scrape off”),[2][3][4][5] through its participial stem ērās-.[6][7][8] The Latin verb is formed from ē-, a form of ex- (“out”) used before r, and rādō (“to scrape, scratch”),[3][9][10][11] which the American Heritage Dictionary traces to the Indo-European root Proto-Indo-European *rēd-.[9] The same Latin verb is the source of raze, razor, rascal and abrade.[12][5] The OED suggests that in some early examples the English word may be a variant of the obsolete arace (“to uproot”).[6] Johnson (1755) derived it instead from French raser.[13]

Earliest recorded meaning

To scrape or rub out something written or engraved; to strike out or obliterate: 1605, in William Camden's Remaines.[6][3][4] Etymonline dates the word to about 1600,[5] and the Shorter Oxford and the Oxford Dictionary of English put its first use in the late 16th century, as a term of heraldry: the head or limb of an animal erased is shown with a jagged, torn-off edge.[7][8]

Semantic evolution

The heraldic use survives in the participle erased, which Johnson (1755) explained as "plucked off".[7][13] From rubbing out marks on a page the verb was extended to wiping something from the mind or memory (1695)[6][7] and, rarely, to destroying something utterly (1728).[6] Its technical history follows recording: from 1945 it was used of removing the signal from magnetic tape,[6][5] and since 1948 a noun erase named that action, chiefly in combinations such as erase head.[6][7] In computing, to erase data is to replace it on a storage device with characters that represent no data.[14] In American criminal slang of the 1930s, erase meant to kill.[15] The derivatives followed the verb: erasure is recorded from 1734 and eraser from 1790, in American English;[2][3] an eraser is especially a piece of rubber or plastic for rubbing out pencil or ink.[7]
