Woollen is an adjective referring to something made from or relating to wool. It specifically denotes materials, fabrics, or garments that are produced from the soft, curly hair of sheep or other animals with woolly coats. Wool is a natural fiber formed from the fleece or coat of these animals, and it can be processed into yarn or thread to create various woollen items.
Woollen fabrics are known for their excellent insulating properties and warmth. Due to the crimp in the wool fibers, they are able to trap air, creating small pockets that act as thermal protection against the cold. This makes woollen materials highly suitable for winter wear, blankets, and cold-weather accessories.
Woollen items are often characterized by their softness, resilience, and ability to retain heat even when wet. As a result of these unique characteristics, woollen fabrics are frequently used to create sweaters, coats, scarves, socks, and other garments and accessories designed for colder climates.
In addition to providing warmth, woollen textiles are also appreciated for their breathability and moisture-wicking abilities. The natural fibers allow air circulation, while absorbing and evaporating moisture, preventing the accumulation of sweat on the skin. This makes woollen materials comfortable to wear in a wide range of temperatures and activities.
Woollen can also be used metaphorically to describe something that resembles or is similar to wool, such as a woollen texture or appearance.

The word "woollen" is derived from the Middle English word "wolnen" which comes from the Old English word "wullēne". This Old English term was formed by combining "wull" (meaning "wool") with the suffix "-en" (indicating material or product). Additionally, the Old English "wull" derived from the Proto-Germanic word "wullō", and ultimately connects to the Sanskrit word "ūrṇā" (meaning "wool"). As such, "woollen" has an ancient etymology that can be traced back to Indo-European roots.
