古英語のheah(高い)が語源の可能性があり、語源的にはhighと同じ。 ヒープ、塊という意味でhighに由来する。
One grain of sand does not make a heap. A second grain of sand added to the first does not make a heap. Indeed each and every grain of sand, when added to the others, does not make a heap which was not a heap before. Therefore, all the grains of sand in existence can still not a heap make.
