obbligatorie

Obbligatorie is the feminine plural form of the Italian adjective obbligatorio, meaning mandatory or compulsory. It is used to describe rules, requirements, or measures that must be complied with, as opposed to those that are optional. In legal, administrative, and organizational contexts, phrases such as misure obbligatorie or norme obbligatorie are common.

Etymology: the term derives from obbligare, to oblige, which in turn comes from Latin obligare, meaning to bind. The related noun obbligatorietà denotes the state or quality of being obligatory. The form obbligatorie agrees with feminine plural nouns (for example, regole obbligatorie, vaccinazioni obbligatorie).

Usage: the adjective appears across public administration, education, health, and industry to indicate that compliance is required. It contrasts with opzionale or facoltativa (optional). In policy language, the designation signals a legal or contractual obligation rather than a recommendation. It can apply to procedures, documents, registrations, or actions that must be carried out to meet a standard or rule.

Grammar and related terms: as an adjective, obbligatorie agrees in gender and number with the noun it modifies (una regola obbligatoria, regole obbligatorie). The related noun obbligatorietà expresses the obligatoriness of a given rule or requirement. Related concepts include obbligo (obligation) and obbligazione (bond or obligation).
