wampum
Wampum (noun) means Small tube-shaped beads made of polished shell, especially white shell, strung together; once used across eastern North America by Native American peoples for various things, including as jewellery, as money and for keeping records; (countable, archaic) a single such bead.
Etymology
A clipping of wampumpeag ("wampum"), probably borrowed from Massachusett wampompeage, meaning "string of white beads used as money". Compare peag, meaning "string of white beads used as money", which is likewise a clipping of wampumpeag. The sense "common kingsnake" comes from the snake's resemblance to a string of wampum. Cognate with Penobscot wάpαpəyak (singular wάpαpi) and Unami òpapiàk (singular òpapi).
