Syn: -- Usefulness; advantageous; benefit; profit; avail; service.
Usage: -- Utility, Usefulness. Usefulness has an Anglo-Saxon prefix, utility is Latin; and hence the former is used chiefly of things in the concrete, while the latter is employed more in a general and abstract sense. Thus, we speak of the utility of an invention, and the usefulness of the thing invented; of the utility of an institution, and the usefulness of an individual. So beauty and utility (not usefulness) are brought into comparison. Still, the words are often used interchangeably.
