mid-14c., from Old French vernis "varnish" (12c.), from Medieval Latin vernix "odorous resin," perhaps from Late Greek verenike, from Greek Berenike, name of an ancient city in Libya (modern Bengasi) credited with the first use of varnishes. The town is named for Berenike II, queen of Egypt (see Berenice). Figurative sense of "specious gloss, pretense," is recorded from 1560s.
late 14c.; see varnish (n.). Related: Varnished; varnishing.
liquid coating material containing a resin that dries to a hard transparent film. Most varnishes are a blend of resin, drying oil, drier, and volatile solvent. When varnish dries, its solvent portion evaporates, and the remaining constituents oxidize or polymerize to form a durable transparent film. Varnishes provide protective coatings for wooden surfaces, paintings, and various decorative objects. Varnish protects and enhances the appearance of wooden floors, interior wood paneling and trim, and furniture.
