wainscot

Wainscot is a type of wood paneling on a room's walls. Wainscot is often made from oak.

This word's meaning is hard to figure out from looking at it, but the wains part is from a Dutch word that meant "wagon" and the scot part probably comes from a word that means "partition." Put them together, and you've got a word for wood paneling in a room: usually the kind that goes half-way up the wall. Originally, wainscot was a type of foreign oak imported to Britain for use in paneling, before it came to mean the paneling itself.
