ableism (n.)

by 1990 in feminist and lesbian literature, from able (adj.) + -ism. Defined in 1991 as "bias against the physically challenged and differently abled (formerly the disabled or handicapped) by the temporarily abled. The phrase 'blind to the truth' would be an example of ableist language." [U.S. News & World Report, vol. 110] Related: Ableist.
