inutility

Inutility is the state or quality of being of no use; the lack of practical or functional usefulness. The noun is formed from utility with the prefix in- and is used to describe objects, actions, or ideas that do not serve a practical purpose or fail to produce beneficial results. It is distinct from inefficiency, which describes poor performance, and from futility, which emphasizes an absence of meaningful outcomes despite effort.

In philosophy and aesthetics, inutility can be examined as a criterion for value, where something may be appreciated for form, novelty, or ethical considerations despite lacking practical use. In economics or decision theory, the term is uncommon in formal models; more standard terms include disutility or simply lack of utility. Cultural commentary may discuss inutility in relation to obsolescence, waste, or overbuilt technologies.

Examples include a tool designed to operate in a narrow way that cannot be used as intended, a gadget overloaded with features that render it awkward to use, or a policy that incurs costs without measurable benefits. In literature and art, inutility can be used to critique consumer culture or to highlight the tension between function and form.
