Definition of 'Utility'

From: GCIDE
  • Utility \U*til"i*ty\, n. [OE. utilite, F. utilit['e], L. utilitas, fr. utilis useful. See Utile.] [1913 Webster]
  • 1. The quality or state of being useful; usefulness; production of good; profitableness to some valuable end; as, the utility of manure upon land; the utility of the sciences; the utility of medicines. [1913 Webster]
  • The utility of the enterprises was, however, so great and obvious that all opposition proved useless. --Macaulay. [1913 Webster]
  • 2. (Polit. Econ.) Adaptation to satisfy the desires or wants; intrinsic value. See Note under Value, 2. [1913 Webster]
  • Value in use is utility, and nothing else, and in political economy should be called by that name and no other. --F. A. Walker. [1913 Webster]
  • 3. Happiness; the greatest good, or happiness, of the greatest number, -- the foundation of utilitarianism. --J. S. Mill. [1913 Webster]
  • 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. [1913 Webster]
