A pillow is a soft cushion that a person puts under their head when they are sleeping in a bed.
A pillow is made from two pieces of cloth that are sewn together and stuffed with a soft material, such as feathers, duck down, or synthetic batting (man made soft stuffing). Pillows are usually rectangular. Pillows are covered with a fabric sheet called a pillowcase. The pillowcase protects the pillow from getting dirty.
The word pillow comes from Middle English pilwe, from Old English pyle (akin to Old High German pfuliwi) and from Latin pulvinus. The word pillow was first known to be used before the 12th century.[1]
