The word “health” comes from the Old English word “hǣlth,” which is derived from “hāl,” meaning “whole” or “well.” This is closely related to the Old High German word “heil” and the Old Norse word “heill.” The concept of health in these languages is deeply tied to the idea of wholeness, completeness, and well-being. The modern English word “health” retains these connotations, referring to the state of being free from illness or injury, as well as overall physical and mental well-being.
