The word “indefinite” has been employed with a broad spectrum of meanings in literature, ranging from descriptions of temporal or quantitative vagueness to expressions of conceptual ambiguity. In some texts, it defines duration or extent in an imprecise manner—as when characters are told to sit in silence for an “indefinite period” [1] or when promises and salary terms are described as “indefinite” [2, 3]. In other contexts, “indefinite” is used to denote a lack of clarity or precision, such as the blurred and vague qualities in visual descriptions [4, 5] or the uncertain nature of abstract mental states, as noted in discussions on the limits of knowledge [6, 7]. Beyond these narrative uses, the term also figures prominently in grammatical classification, distinguishing between demonstrative and indefinite pronouns [8, 9, 10]. Whether characterizing the physical, temporal, or conceptual, “indefinite” serves to highlight areas of uncertainty and unboundedness across genres and disciplines [11, 12, 13].
