Definition

A protective coating applied to wood or other surfaces that dries to a hard, glossy finish; or metaphorically, a superficial covering or deceptive exterior that conceals something less attractive. As a verb, to coat with varnish or to gloss over with an appearance of propriety.

Example Usage

The decorator applied three coats of varnish to protect the mahogany table from water damage.

Origin

From Old French 'vernis', possibly from medieval Latin 'vernix' or Persian origins through Venetian trade routes.

Fun Fact

Traditional varnishes were made from tree resins dissolved in oil, while modern varnishes often use synthetic resins and various solvents for different durability and finish qualities.
