Other forms: cashmeres
Cashmere is an extremely soft wool that comes from a particular kind of goat. The goat itself is also called a cashmere.
When you knit a sweater from cashmere, you end up with a garment that's much softer and less itchy than regular wool. You can use the same word when you describe the fabric itself, and things made with it: "I want a red cashmere scarf for my birthday." In the 17th century, the word specifically meant "a cashmere shawl," from Kashmir, the region of the Himalayas where this type of goat originated.
