erase: [17] Like abrade, rascal, rase and razor, erase comes ultimately from Latin rādere ‘scrape’. This formed the basis of a compound verb ērādere ‘scrape out, scrape off’ (its first element is the Latin prefix ex- ‘out’). Eraser ‘rubber’ seems to be a 19th-century coinage. => abrade, rascal, rase, razor
erase (v.)
c. 1600, from Latin erasus, past participle of eradere "scrape out, scrape off, shave; abolish, remove," from assimilated form of ex- "out" (see ex-) + radere "to scrape" (see raze). Of magnetic tape, from 1945. Related: Erased; erasing.
