Reservuaarisse

Reservuaarisse is the illative case form of the Estonian noun reservuaar, meaning a reservoir or storage facility for liquids such as water or fuel. The illative form marks direction toward the reservoir, as in sentences describing movement into the reservoir.

Etymology and form

Reservuaar is a loanword in Estonian, derived from the French réservoir. In Estonian morphology, the illative suffix -sse attaches to the noun to indicate movement into a place or container. Therefore reservuaarisse corresponds to “into the reservoir.” The base noun reservuaar has plural reservuaarid and genitive reservuaari, while reservuaarisse remains the singular illative form.

Usage

Reservuaarisse is used in technical, hydrological, and practical contexts to describe actions directed toward a reservoir. Examples include “Vesi voolab reservuaarisse” (Water flows into the reservoir) and “Pumpaja toimib reservuaarisse mineva voolu korral” (The pump operates when power flows into the reservoir). It is not used to refer to the exterior structure in a general sense but specifically to the act or direction of entering the reservoir.
