Definitions

1. A water-repellent mixture of fats or oils used primarily for preserving and waterproofing leather goods

Etymology: Leather workers once used "dub" as a plain verb meaning to work a fat or grease into hide so it stays soft and resists water. The noun "dubbin" is the product that job calls for: the grease itself, often mixed with tallow, wax or oil. The verb is much older than the noun, and its exact origin is uncertain. Dubbin is still sold for boots, saddles and work gear. Its name shows the trade it came from, since the substance is defined by what it does to leather rather than by any particular ingredient.
