Repellency refers to the quality or ability of a substance or object to repel, deflect, or resist the adherence, penetration, or absorption of another substance or external force. It is the inherent property of a material that allows it to discourage or prevent contact or interaction with other substances, organisms, or elements.
In the context of materials, repellency often refers to the ability to resist the adherence or absorption of liquids, such as water, oils, or chemicals. For example, water repellency is the property of a surface or fabric that prevents the penetration or absorption of water, making it waterproof or water-resistant. This characteristic can be important in various applications such as outdoor apparel, raincoats, tents, or protective coatings.
Repellency can also pertain to the ability of an object or substance to deter or ward off the presence of insects, pests, or animals. In such cases, repellency often relies on the emission of specific chemicals or odors that are unpleasant or noxious to the targeted organisms, thus keeping them at bay.
Overall, the concept of repellency encapsulates the idea of resistance against undesirable substances or forces, ranging from liquids to organisms, thereby providing protection or maintaining the integrity of a material, object, or environment.

The word "repellency" is derived from the verb "repel", which ultimately traces back to the Latin word "repellere". In Latin, "repellere" is composed of the prefix "re-" meaning "back" or "away", and the verb "pellere" meaning "to drive" or "to push". Over time, "repellere" evolved into the Old French word "repellir", which then entered Middle English as "repellen", meaning "to repel" or "to force back". From this verb form, the noun "repellency" was created to refer to the quality or state of being repellent or having the ability to repel.
