Fiberfill → The word is formed from "fiber" (from Latin "fibra", meaning a thread or filament) and "fill" (from Old English "fyllan", meaning to make full). Fiberfill refers to a material made of fibers that is used to fill or stuff items, making them fuller or more cushioned.
Think of 'fiber' as a thread that helps to 'fill' something up, which is exactly what fiberfill does.
