remediation

Etymology

It is borrowed from Latin remediātiō (“process of curing or healing”),^[2][3][4][5] from the past participle of remediō (“to remedy, heal”),^[2][3][6] from remedium (“a cure, remedy”),^[6][5] which is formed from re- and medeor (“to heal”), from Proto-Indo-European *med- (“to take appropriate measures”).^[6] In post-classical Latin the noun also meant a remedy, in a 15th-century British source.^[2] The OED compares the earlier English adjective remediate and the later verb remediate;^[2] Etymonline dates the verb to 1961, as a back-formation from remediation, and suggests that the newest uses of the noun may be fresh formations from it.^[6]

Earliest recorded meaning

The action of remedying or correcting something: 1794, in J. Owen's Retrospect.^[2] Etymonline and Merriam-Webster Unabridged date the word to 1818,^[6][3] and Dictionary.com to 1810–20.^[7]

Semantic evolution

From the general sense of remedying, the word was used in medicine from 1850 for the application of a remedy, a use now rare.^[2] In the 20th century it took on two specialised senses.^[2][6] In education it meant teaching or training given to correct a deficiency, recorded by the OED from 1933 and often used attributively,^[2] and by Etymonline in educational jargon by 1966.^[6] In environmental use it meant cleaning up a polluted site by removing or neutralising contaminants, from 1980 in the OED^[2] and by 1986 in Etymonline,^[6] and Collins now gives the reversal or stopping of environmental damage as its main use.^[8]
