extendery

Extenderies are a theoretical concept in linguistics and philosophy, referring to hypothetical entities or concepts that possess the quality of "extending" or "being extended" in some fashion. This notion often arises in discussions about the nature of space, time, and the physical world. For instance, when considering an object, an extender is that aspect of it which occupies space. This is distinct from other properties an object might have, such as color or temperature, which are not inherently spatial.

The term can be applied to various domains. In physics, the concept of extensiveness is crucial when discussing physical quantities like mass or energy. An extensive property is one that is additive; if you combine two systems, the total property of the combined system is the sum of the properties of the individual systems. For example, the total mass of two objects is the sum of their individual masses. This contrasts with intensive properties, such as temperature or density, which do not add up when systems are combined.

Philosophically, the idea of an extender might relate to debates about the mind-body problem. If the mind is considered non-physical, it would lack the extensorial qualities of the physical body, such as occupying a specific location in space or having a measurable volume. The concept helps to delineate between different kinds of existence and properties, serving as a tool for conceptual analysis rather than referring to a concrete, observable entity. The precise definition and application of "extender" can vary depending on the specific theoretical framework being employed.
