Terminology and the Well-Formed Definition, R. A. Strehlow

Abstract: A classification of definitions is developed, incorporating the concept of the well-formed definition. The classification is discussed with emphasis on its usefulness in the process of writing definitions. The well-formed definition (one that is brief, clear and generally useful) is a concept that provides an analytical capability to distinguish between definitions and descriptions. If even one of the three characteristics of brevity, clarity, or general usefulness is absent, a definition is better considered a description.
