Etymology: "Overhydration" is a plain compound: the prefix "over-" ("too much") attached to "hydration," the act or process of supplying water to something. "Hydration" itself comes from the Greek "hydor," meaning water, combined with a suffix for the process of becoming or being treated with something, so the whole word literally means too much water-treatment of the body. The logic is the same as "overeating" or "overwork": "over-" marks an excess of the base action. In medicine, the word describes a body holding more water than it can handle, which can dilute blood sodium and disturb normal function. Its formation follows the modern pattern of pairing a productive prefix with an established term, so it is a straightforward coinage rather than a word with a dramatic shift in meaning.
