Other forms: moccasins
If you lose a moccasin on your way to work, it means you'll be walking around with only one shoe all day. A moccasin is a soft leather slip-on shoe.
Virginian Algonquins get credit for the word moccasin, though a relative of it existed in other American Indian languages to designate a leather shoe so elegant in design that it's now known around the world. Less well known, perhaps, is the correct spelling, which you see here. Everyone seems to know there's a double letter but fewer remember that it's the c, not the s.
