rehabilitate

Etymology

It is borrowed from Medieval Latin rehabilitātus, the past participle of rehabilitō (“to restore to a former rank, re-establish”);^{[2][3][4][5][6][7]} the OED, revised in 2009, takes it from the past-participial stem and records the Medieval Latin verb in British sources from about 1400.^[8] The Latin verb is formed from re- (“again”) and Late Latin habilitō (“to make fit, enable”),^[3][2][4][8] from habilis (“easily handled, fit”).^[4][9] Barnhart and Etymonline take the English verb as possibly, or partly, a back-formation from rehabilitation,^[4][9] which the OED records from 1483.^[8] The OED also compares Middle French réhabiliter (“to restore to former rights or status”), recorded from 1456, and earlier in Old French in the phrase giving a town the right to have a mayor.^[8]

Earliest recorded meaning

To restore a person by official decree to former privileges, rank or possessions: 1580–1, in the Register of the Privy Council of Scotland; the OED marks this sense as originally Scottish.^[8] Barnhart dates it 1580–81 and Etymonline to the 1580s, both with the sense of restoring someone to a former rank, privilege or standing.^[4][9] Merriam-Webster Unabridged gives about 1581.^[3]

Semantic evolution

The Century Dictionary, quoted by Etymonline, called it a term of civil and canon law, and Fitzedward Hall wrote in 1873 that the old legal word had been gaining ground since Burke brought it into popular use, perhaps prompted by the French verb.^[9] From 1663 it was used more generally of restoring something to a previous condition,^[8] and Etymonline finds it in popular use by 1845 for bringing something back after decay or damage.^[9] The sense of restoring someone's reputation is recorded from 1731, especially of a literary or historical reappraisal;^[8] Etymonline dates it to 1847.^[9] The 19th century added the senses that are now the commonest: reforming an offender through education and work (1865), restoring someone to health after illness or injury (1867), rebuilding a country after a war (1867), returning a soldier to civilian life (1890) and, in North America, repairing or renovating a building or vehicle (1878).^[8] The intransitive use, to undergo rehabilitation, appears in 1945.^[8] The clipping rehab is recorded as a noun from 1935, first in New Zealand, Australia and Canada for the resettlement of servicemen, and since 1955 in the United States for the treatment of addicts;^[8] as a verb, of houses, it dates from 1975.^[9]
