What does incapacitate mean?
Incapacitate means to make someone unable to perform an action or function, especially because of illness, injury, incapacity, or legal restriction. The word is commonly used in medical, legal, and workplace contexts: a disease may incapacitate a person, while serious injury can incapacitate an employee temporarily or permanently. Unlike the more general word disable, incapacitate often refers specifically to a person's physical, mental, or legal capacity to act. It can also be used when a person is prevented from carrying out official responsibilities, such as managing personal affairs or serving in a role. The related noun incapacity refers to the state or condition of being unable to act, while the adjective incapacitated describes someone who has been made unable to function. Because the term can sound clinical and severe, it is generally more appropriate for substantial limitations than for ordinary inconvenience.
verbTo make someone physically or mentally unable to do something, or to deprive someone of the capacity to act. It can also refer to making someone legally incapable of doing something.
- To make someone physically or mentally unable to perform an activity or function.
- To deprive someone of the legal or practical ability to act, manage their affairs, or perform a role.
"The injury incapacitated him for the remainder of the season."
"The illness incapacitated him for several months."
"The court ruled that the defendant was incapacitated and unable to manage her own affairs."
Incapacitate comes from the same Latin capacity that describes what someone is capable of doing: remove the capacity, and the person becomes incapacitated.

Where does incapacitate come from?
Incapacitate was formed in the early 19th century from the Latin root capac-, meaning “able to hold or capable,” together with the prefix in- and the suffix -ate. It developed alongside related English words such as capacity, capable, and capacious, all of which reflect the idea of capacity or the ability to contain or act. The word originally expressed the making or rendering of a person or thing unable to act, a sense that continues in modern medical and legal usage.
