The word "郧西县" is formed by combining three characters: "郧", a historical name for a region or river; "西", meaning "west", indicating its geographical position relative to that region; and "县", meaning "county", designating its administrative division. Together, they create a place name meaning "Yunxi County", where "Yun" is the root, "xi" specifies a westward location, and "xian" denotes its status as a county.
