In literature, the word "retrospective" is often employed to evoke a reflective, backward-looking quality that both colors character emotion and frames narrative analysis. Authors use it to signal a deliberate reexamination of past events or feelings, as in the reflective tone of a "retrospective smile" or a contemplative look back on earlier experiences ([1],[2]). It can also serve a more analytical purpose, designating reviews or judgments of preceding actions, whether in philosophical musings or legal contexts, as seen when discussing the effects of past actions or laws ([3],[4]). Moreover, its inclusion in titles or chapter headings emphasizes a structural or thematic return to earlier periods or ideas, underscoring how the past continuously informs and shapes subsequent perceptions ([5],[6]).
