What does spastic mean?
Spastic is a word whose history illustrates how medical vocabulary can become pejorative in ordinary speech. It derives from Greek roots associated with pulling or contraction and was formerly used in medicine for conditions involving involuntary muscle contraction, stiffness, or paralysis. The older clinical adjective remains familiar in historical texts, but current medical writing generally uses more precise expressions such as spasticity, increased muscle tone, or hypertonia. The noun became a longstanding term for a person with such a disability and has since developed a strongly offensive use as an insult, particularly in relation to someone’s movement or speech. Spastic is also used as an informal verb for making a jerky imitation of another person, usually with mocking intent. Consequently, although the word can clarify the history of medical terminology, using it about a living person without a specific and appropriate clinical purpose is likely to cause harm.

Where does spastic come from?
The word comes through Latin from Greek spastikos, meaning liable to spasm or contraction. It is related to Greek spastē, a drawing or pulling, and to forms such as spasm and spasmodic. The medical term developed from this meaning before the noun and verb acquired their offensive and mocking uses.
