necesarias

Necesarias is the feminine plural form of the Spanish adjective necesario. It describes something that is required, indispensable, or essential for a given purpose, and it agrees with feminine plural nouns (for example, herramientas necesarias, medidas necesarias, recursos necesarios).

Usage and nuance: Necesarias can modify a wide range of feminine plural nouns to indicate obligation or necessity. It is common in everyday language, technical writing, and formal contexts. In phrases where the exact type of necessity is less specified, it may be paired with verbs such as son, resultan, or requieren (por ejemplo, son necesarias estas medidas). The expression lo necesario uses the neuter, broader sense of “the necessary things” or “what is required,” often referring to essential elements in general terms.

Etymology: Necesarias derives from the Latin necessarius, the feminine plural form of the adjective necessary/indispensable, which itself comes from necessitas, meaning necessity or need. The word shares cognates with other Romance languages and with the English word necessary through the same Latin root.

Related terms: Necessary is often translated as indispensable (indispensables), required (requeridas/obligatorias), or essential (esenciales), depending on context. The masculine singular form is necesario, and the feminine singular form is necesaria.
