one of the Great Lakes, named for a native Iroquoian people who lived nearby, from French Erie, shortening of Rhiienhonons, said to mean "raccoon nation," perhaps in reference to a totemic animal.
Lake bordered by Ontario, Canada, to the north; New York to the east; Pennsylvania and Ohio to the south; and Michigan to the west.
Note: Fourth largest of the Great Lakes, it has been known for years for its high level of pollution.
