The word "indifferently" is deployed in literature to convey a sense of casual detachment or lack of passionate engagement in both action and speech. In works of fiction, characters often speak or act indifferently to suggest nonchalance or dismissal—for instance, a character’s muted response may signal emotional reserve or subtle irony (e.g. [1], [2], [3]). At times, it also appears in more descriptive passages where actions or natural phenomena are rendered with a sense of impartiality or routine occurrence, as when certain behaviors, elements, or supplies are handled without special care (e.g. [4], [5], [6]). In scholarly and rhetorical contexts, it is used to denote interchangeable uses or undifferentiated applications, underscoring an absence of strict distinction in usage (e.g. [7], [8], [9]). Overall, this modest adverb encapsulates a wide spectrum of attitudes, ranging from casual indifference in everyday dialogue to an analytical statement of equivalence in more formal or theoretical discourse (e.g. [10], [11]).
