The sorites paradox (from Ancient Greek: σωρείτης sōreitēs, meaning “heaped up”) is a paradox that arises from vague predicates. The paradox of the heap is an example of this paradox which arises when one considers a heap of sand, from which grains are individually removed. Is it still a heap when only one grain remains? If not, when did it change from a heap to a non-heap?
