We present and analyze a thermodynamical theory of rheology with singleinternal variable. The universality of the model is ensured as long as themesoscopic and/or microscopic background processes satisfy the appliedthermodynamical principles, which are the second law, the basic balances andthe existence of an additional-tensorial-state variable. The resulting model,which we suggest to call the Kluitenberg-Verh\'as body, is thePoynting-Thomson-Zener body with an additional inertial element, or, in otherwords, is the extension of Jeffreys model to solids. We argue that thisKluitenberg-Verh\'as body is the natural thermodynamical building block ofrheology. An important feature of the presented methodology is that nontrivialinequality-type restrictions arise for the four parameters of the model. Wecompare these conditions and other aspects to those of other knownthermodynamical approaches, like Extended Irreversible Thermodynamics or theoriginal theory of Kluitenberg.
