Correct spelling for the English word "whiskers" is [wˈɪskəz], [wˈɪskəz], [w_ˈɪ_s_k_ə_z] (IPA phonetic alphabet).
Whiskers refer to the long, stiff hairs that grow near the mouth, nose, and other areas of the face in certain mammals. They are commonly found in animals such as cats, dogs, and rodents, serving as sensory organs that aid in navigation and perception. Whiskers, also known as vibrissae, are embedded deeper in the skin than ordinary hairs, and their roots are attached to specialized muscle fibers, making them more sensitive.
Functionally, whiskers play a crucial role in tactile sensing. They serve as extensions of the animal's nervous system, providing vital information about its surroundings. By bending when they come into contact with objects or changes in air currents, whiskers convey valuable tactile information to the animal, such as the presence of obstacles in their path, wind direction, or even the texture and shape of objects nearby. This sensory input helps animals navigate their environment, hunt for prey, detect potential threats, and maintain spatial awareness.
In addition to their functional importance, whiskers are also considered a defining physical characteristic of many animal species. In felines, whiskers are typically long, straight, and the same width as the animal's body. They protrude from the sides of the upper lip and can vary in length depending on the individual and breed. Whiskers are shed and regrown periodically in most animals, ensuring their effectiveness as sensory organs. Overall, whiskers are an integral part of the anatomical and sensory adaptations that enable animals to interact with their surroundings.

It is derived from the verb "whisk" which came from the Old Norse word "visk" meaning "anything that is moved quickly".
