Wooden paneling covering the lower part of an interior wall.

Etymology
The probable Dutch or Flemish components mean “wagon” and “partition”; the oak may have been named for use in wagon building, though the connection is uncertain. The name shifted from high-quality oak to wall panels made from it.
