An Opassom hath an head like a Swine, and a taile like a Rat, and is of the bignes of a Cat. Under her belly she hath a bagge, wherein shee lodgeth, carrieth, and sucketh her young.
So wrote Captain John Smith in 1608, bringing the Virginia Algonquian word into English.
from op ‘white’ + assom ‘dog’
