This article explores the effects of naming and describing disability in law and medicine. Instead of focusing on substantive issues like medical treatment or legal rights, it will address questions which arise in relation to the use of language itself. When a label which is attached to a disability is associated with a negative meaning, this can have a profound effect on the individual concerned and can create stigma. Overly negative descriptions of disabilities can be misleading, not only for the (...) individual, but also more broadly in society, if there are inaccurate perceptions about disability in the social context. This article will examine some relevant examples of terminology, where these issues arise. It will also suggest that the role of medicine and the law in naming and describing disability is particularly important because in these areas there is, perhaps more than anywhere else, a recognized source of authority for the choice of terminology. Labels and descriptions used in the medical and legal contexts can not only perpetuate existing stigmatization of disabled people, but can also contribute to creating stigma at its source, given that the words used in these contexts can constitute an exercise of power.
