adjectival forms as nouns

do not use adjectives as nouns when referring to something that describes only a part of a person's or a group's existence. Undesirable constructions: the blind, the poor, the learning disabled, the elderly, an amputee, a diabetic, a quadriplegic. In most cases, it doesn't help to simply put a noun after the adjective. You usually need to change the construction itself: those who have been blind from birth, poor and low-income renters, children with learning disabilities, older patients, someone with an amputation/with diabetes/with quadriplegia. See also disabilities, "people first" rule.
