disable

Etymology

It is inherited from Middle English disablen,^[2] formed from English dis- + able,^[3][4][5][6] originally after Anglo-Norman desabler (“to deprive of a legal right”),^[3] which the Anglo-Norman Dictionary records from 1302 and the OED from about 1275 or earlier.^[7][3] The OED takes the second part as either the adjective or the verb able, and Etymonline as the Middle English verb ablen (“to make fit”).^[3][6] The adjective comes from Old French able (“capable, fitting”), from Latin habilis (“easily handled, apt”), from habeō (“to have, hold”).^[6][8] The verb unable, "to make unfit", was used earlier in the same sense.^[6][3]

Earliest recorded meaning

To make or declare legally incapable: 1445, in the Rolls of Parliament.^[3][4] Dictionary.com dates the word 1475–85.^[9]

Semantic evolution

The legal sense came first, after the Anglo-Norman verb.^[3][7] The physical sense, to make a person or animal incapable of activity, especially through injury or illness, followed before 1492, in Caxton's translation of the Vitas Patrum,^[3] and in 1582 the word was used generally for putting something out of action.^[3] From 1528, in Skelton, it could also mean to belittle or disparage;^[3] Trench explains that to injure a person's character was felt to be the surest way of disabling him, and quotes Shakespeare's As You Like It and Bacon's Essays for this sense.^[10] Johnson (1755) gave first the sense "to deprive of natural force; to weaken".^[11] A sense "to make of no force or validity" was used from 1548 to 1693.^[3] The modern technical sense, to switch off a device or function deliberately, is recorded from 1932, in the Bell Telephone Quarterly,^[3] and the noun disable, an act of deactivating, from 1827.^[3] The adjective disable, unable, was used from before 1500.^[3]
