Rezervorul

Rezervorul, in Romanian, is the definite form of the noun rezervor, meaning a reservoir or a tank. It designates a container or a natural or artificial body of water used for storing liquids or gases, or more generally a space or vessel that stores substances or energy. The term is widely used across hydrology, engineering, energy, and everyday language.

Etymology and grammar: rezervorul derives from rezervor, with the definite article suffix -ul forming the masculine singular noun. The plural form is rezervoarele. In different contexts the word may be preceded by adjectives such as de apă (water), de combustibil (fuel), or de ulei (oil), e.g., rezervorul de apă potabilă or rezervorul de combustibil.

Common contexts: In hydrology and water management, rezervorul refers to a water reservoir used for drinking water supply, irrigation, flood control, or hydroelectric power. In engineering and industry, it denotes a storage tank for liquids or gases, such as rezervor de combustibil (fuel tank), rezervor de ulei (oil reservoir), or rezervor industrial. In automotive and aeronautical terminology, the term is used for fuel tanks and related storage containers. The word also appears in general descriptions of machinery and processing plants where liquids require containment.

Notes: rezervorul is usually contrasted with cisternă, which can denote a larger or more specialized storage tank in some contexts. Plurals are rezervoarele, and the term remains common in technical manuals, infrastructure planning, and everyday speech.
