Sense: noun/1
Mound, hill, knoll, and heap all describe raised collections of material, but they differ in size, shape, and origin. A mound is typically small to medium-sized, often man-made or created by animals, and has a rounded, smooth shape — for example, an ancient burial mound or an ant mound. A hill is larger and almost always natural, rising noticeably above the surrounding land. A knoll is a small, round hill that stands alone in an open area. A heap, by contrast, is less structured: it suggests loose material thrown together without shaping. You might heap sand into a pile at the beach, but you would not call that heap a mound unless you deliberately smoothed it into a rounded shape. In cooking, you would say 'a mound of mashed potatoes' to describe a neatly rounded serving, whereas 'a heap of mashed potatoes' sounds sloppier.

Etymology
The word 'mound' entered English in the 16th century, probably from an Old Germanic source related to protection. Its earliest meaning in English was 'a defensive fence or wall' — the same idea as the verb sense 'to enclose or fortify.' Over time, the meaning shifted from the wall itself to the pile of earth used to build it, and then to any raised, rounded heap of material. The baseball sense (the pitcher's mound) appeared around 1912.
