Wheat bristle is a type of stiff, coarse fiber that is obtained from the stem of wheat plants. It is commonly used for making brushes, brooms, and other cleaning tools. The term 'AWN' is an abbreviation for the word 'AWNING, ' which is a covering made of canvas or other material that is stretched over a frame of poles or ropes. Awnings are often used to provide shade and protection from the elements.
