Decorative treatment
This area is given a decorative treatment different from that for the upper part of the wall; for example
panelling,
wainscoting or
lincrusta. The purpose of the dado treatment to a wall is both aesthetic and functional. Historically, the panelling below the
dado rail was installed to cover the lower part of the wall which was subject to stains associated with rising damp; additionally it provided protection from furniture and passing traffic. The dado rail itself is sometimes referred to misleadingly as a chair rail, though its function is principally aesthetic and not to protect the wall from chair backs.
Derivation

The name was first used in English as an
architectural term for the part of a pedestal between the base and the
cornice

. As with many other architectural terms, the word is Italian in origin. The dado in a pedestal is roughly cubical in shape, and the word in Italian means "dice" or "cube" (ultimately Latin ''
datum'', meaning "something given", hence also a die for
casting lots).
By extension, the dado becomes the lower part of a wall when the pedestal is treated as being continuous along the wall, with the cornice becoming the dado rail.
