Definition

Adjective: * Resistant to water penetration: Describes a material or surface that causes water to bead up and roll off rather than being absorbed. It is a less absolute quality than "waterproof," as it can resist light rain or moisture for a period but may eventually become wet under sustained exposure.

Usage

The adjective "water-repellent" is used to describe items designed to protect against moisture. It typically precedes the noun it modifies. * It is a property applied to fabrics, coatings, and finishes. * It is often used in product descriptions for outdoor gear and clothing.

Examples

• Adjective:
  • This jacket is made from a water-repellent fabric, perfect for a light drizzle.
  • The hiker applied a water-repellent spray to his boots.
  • The tent's water-repellent coating kept the interior dry during the brief shower.

Advanced Usage

  • The outer shell is water-repellent, but the seams are sealed to make the overall garment waterproof.
