inagotable

Inagotable is an adjective in Spanish used to describe something that cannot be exhausted or depleted, and to characterize people or efforts marked by persistent energy or stamina. It can refer to resources, ideas, or emotional or physical vigor, and is used in both literal and figurative contexts.

Etymology and forms: The word is built from the negating prefix in- attached to agotable (capable of being exhausted), from agotar, to exhaust. Thus inagotable literally means not exhaustible. The adverb form is inagotablemente, and the noun form can appear as inagotabilidad or in phrases such as una fuente inagotable. In other Romance languages there are close equivalents, such as inagotável in Portuguese and inagotabile in Italian; a common French cognate is inépuisable.

Usage: Inagotable is frequently employed to praise or describe enduring qualities, such as a person’s perseverance or a resource that seems limitless. Examples include "una fuente inagotable de ideas" (an inexhaustible source of ideas) and "trabaja inagotablemente" (works tirelessly). It is common in literary, journalistic, and everyday language.

See also: agotable (exhaustible) and inépuisable (French cognate meaning inexhaustible). The term remains a standard descriptor in Spanish for both concrete and abstract forms of inexhaustibility or tireless effort.
