Etymology: Groundwaters is simply the plural of groundwater, so it describes several bodies or kinds of water held beneath the surface rather than a single reservoir. The base word is a plain English compound: "ground" comes from Old English "grund", meaning the bottom or base of something, and "water" comes from Old English "wæter". Joined together, they describe water sitting in the ground itself. Both halves are old inherited words, descended from Proto-Germanic forms, so the compound is a native English creation rather than a borrowing from Latin or French. Its meaning follows directly from its parts: the "ground" in the compound refers to the soil and rock layers that water saturates, not to the surface people walk on.

Synonyms: aquifers, subsurface water, underground water
