Invalid Definition
An invalid is a person who is unable to walk or move independently, and who therefore relies on a wheelchair or other form of assistance for mobility. The term ‘invalid’ is also used to describe someone who is sick or injured, and as a result, is unable to participate in usual activities.
The word ‘invalid’ has come to be seen as a negative term, with connotations of being weak or incapable. This is not the intended meaning of the word, but rather an unfortunate side effect of its use. When referring to someone who uses a wheelchair or other mobility aid, it is important to be respectful and use language that does not convey negativity or pity.
