The term "defective" assumes a remarkably diverse range of meanings in literature, serving as a descriptor not only of linguistic and grammatical incompleteness but also of broader conceptual, structural, and moral shortcomings. In the realm of classical studies, it is used very technically to denote words that lack a full complement of forms or cases, as noted in discussions of Latin grammar ([1], [2], [3], [4], [5]). Beyond linguistics, the adjective appears in philosophical and analytical texts to critique insufficient reasoning or incomplete analyses—Kant, for instance, points to a definition that is necessarily defective ([6]), while Rousseau uses it to describe impaired economic circulation ([7]). The word further conveys physical and systemic deficiencies, such as unstable architectural foundations or flawed organizational capacities ([8], [9], [10], [11]), and even extends into characterizing shortcomings in personal abilities or the elusive quality of reality in imaginative art ([12], [13], [14]). Through these varied applications, "defective" consistently highlights the notion of something falling short of an expected or ideal state.
