moccasin (n.) Look up moccasin at Dictionary.com
"North American Indian shoe" (made of deerskin or soft leather), 1610s, from an Algonquian language of Virginia, probably Powhatan makasin "shoe," from Central Atlantic Coast Algonquian *mockasin, similar to Southern New England Algonquian *makkusin, Munsee Delaware mahkusin, Ojibwa makizin. The venomous snake of southern U.S. (1784) is perhaps a different word, but Bright regards them as identical.
