Inability, or incapacity, refers to the lack of ability or power to perform a specific task or function. This can be due to various factors, including physical limitations, mental health issues, or developmental disorders. For example, a person with a disability may face challenges in completing daily activities that others can do easily. In legal contexts, incapacity can affect a person's ability to make decisions or enter into contracts. When someone is deemed legally incapacitated, they may require a guardian or power of attorney to manage their affairs. This ensures that their rights and interests are protected when they cannot act on their own behalf.
