dellutilità

Dellutilità, often written dell’utilità in Italian, is a term used to refer to the concept of usefulness or value across disciplines. It appears in phrases such as valore dell’utilità, utilità marginale, or funzione di utilità and functions mainly as a linguistic marker rather than a distinct discipline in itself.

Etymology: The term derives from utilità, meaning usefulness or benefit, with the contracted form dell’ used before vowels. The root utilitas comes from Latin, and the Italian term has wide usage in economics, philosophy, and law.

In economics and decision theory, utility describes the subjective satisfaction or usefulness that a person derives from a good or service. Analyses often distinguish cardinal from ordinal utility and employ the utility function to model choices under constraints. Utility theory supports welfare analysis, consumer choice modeling, and explanations of resource allocation under scarcity.

In law and public policy, the notion appears in phrases such as servizi di pubblica utilità (public utilities) and di particolare utilità pubblica (of particular public usefulness). The concept signals services or arrangements considered essential for society, with implications for regulation, pricing, service provision, and, in some contexts, expropriation or public interest considerations.

In philosophy and ethics, the notion of utility is central to discussions of consequences and welfare, particularly within utilitarian frameworks. The Italian term is often linked to utilitarismo, the doctrine that actions are right if they promote overall utility or happiness.
