Not to be confused with "collection" or "pile", the hoard is indicative of an entity in and of itself. This collection is the whole rather then a collection of individual pieces. Therefore, it must be treated as an entity, and not a mere collection of pieces with similar properties.
Example: A hoard is made up of not one but any number of items intentionally accumulated in a specific environment. Such as the individual piece of plastic, that has its own properties, the hoard has it's own properties that are not defined by the individual piece of plastic but rather the properties associated with the whole of them.
