What does incapability mean?
Incapability means a lack of ability, power, or capacity to act, think, or perform a particular function. It can describe a person's limitations as well as the inability of an organization, system, or group to achieve something. In legal and medical contexts, it may refer to a specific disability, such as an inability to consent or to manage one's affairs independently. The noun is especially associated with formal, institutional, and legal language, so in ordinary conversation inability is often the more natural choice. The word is useful when the emphasis is on a limitation itself rather than simply on the absence of a particular skill or opportunity. It can also carry a sense of powerlessness or ineffectiveness, especially when describing a group's inability to respond to a problem.

Incapability was formed in the early 19th century from the adjective incapable, which combines the Latin prefix in- meaning “not” with capable. Capable comes through French from Latin capax, meaning “able to hold or capable,” ultimately from capere, “to take” or “seize.” Related English words include capability, captive, capture, and captivate.
