coinstantiation

Edward MacNeal was pointing out the ubiquity of coinstantiation in daily life when he explained regarding apples and oranges (both literal and proverbial) that "we must feel free to redefine apples and oranges as fruit, missiles, paperweights, or theatrical props as suits our changing needs; then we can observe the rules of addition and have the result make sense."

A baseball can be a coinstantiation of the concepts of a ball, a piece of sporting goods, a toy, a collectible, and a memento.
