- tuxedo - the etymology1 is worth citing in extenso.
1889, named for Tuxedo Park, N.Y., site of a country club where it first was worn in 1886. The name is an attractive subject for elaborate speculation, e.g.:
The Wolf tribe in New York was called in scorn by other Algonquians
from tuksit: round foot, implying that they easily fell down in surrender. In their region thus came the names Tuxedo and Tuxedo Lake, which were acquired by the Griswold family in payment of a debt. There the family established the exclusive Tuxedo Club, and there in the late 1880s Griswold Lorillard first appeared in a dinner jacket without tails, a tuxedo. By a twist of slang, one may now refer to a man in a tuxedo as a 'wolf. [Shipley]
But in another version of the story, p'tuksit was the Algonquian word for "wolf," the animal, perhaps from the shape of its paws. The authoritative Bright, however, says the tribe's name probably is originally a place name, perhaps Munsee Delaware (Algonquian) p'tuck-sepo "crooked river." Short form tux is attested from 1922.
skunk - meaning "urinating fox".
Algonquian language (probably Abenaki) seganku, from Proto-Algonquian */šeka:kwa/, from */šek-/ "to urinate" + */-a:kw/ "fox."
cariboo - meaning "scratcher"
caribou, from Micmac (Algonquian) kaleboo, lit. "pawer, scratcher," from its kicking snow aside to feed on moss and grass, or a related Algonquian name
opossum - meaning "white animal".
from Powhatan (Algonquian) apasum "white animal."
wampum - meaning "string of white". (credits to @The Raven)
shortened from wampumpeag (1620s), from Algonquian (probably Narragansett) wanpanpiak "string of white (shell beads)," from wab "white" + ompe "string" + pl. suffix -ag.
- Squash (pumpkin) - meaning "green things that may be eaten raw"
Shortened borrowing from Narraganset (Algonquian) askutasquash, lit. "the green things that may be eaten raw," from askut "green, raw" + asquash "eaten
For Native Americans **everyday life** items
from Massachuset (Algonquian) squa "woman" (cf. also Narraganset squaws "woman")

In addition to the information given above, there is a book-length treatment of this subject in:
Cutler, Charles L. O Brave New Words: Native American loanwords in current English. Norman : University of Oklahoma Press, 1994. 286 pages.
It's an enjoyable read.
