The word "unaccountable" is used across literary genres to denote that which defies logical explanation or predictable behavior. In fairy tales and mysteries alike, authors employ it to evoke puzzlement or highlight inexplicable qualities; for example, Andersen uses it to describe a shadow's grimace in a way that suggests something beyond rational comprehension ([1]), while Jane Austen and Dostoyevsky apply it both to characters’ behavior and to their inner dispositions, as seen in the inexplicable conduct noted in Sense and Sensibility and Crime and Punishment ([2], [3]). It also finds a place in scientific and philosophical discourse—Darwin refers to it when discussing natural selection, underscoring the unpredictable elements of nature ([4]). Overall, “unaccountable” becomes a tool with which writers mark the mysterious and the extraordinary, whether in the subtleties of human emotion or the wonders of the natural world.
