The word can functions as a versatile modal verb in literature, often highlighting ability, possibility, or potential while also sometimes signaling permission or inevitability. Its usage can denote what a character is capable of doing, as in asserting strength or talent, or what is merely possible, as when fate or circumstances limit action. It is employed to frame rhetorical questions, such as wondering if doubt exists about leadership [1], while also reflecting internal conflicts or constraints, for instance in declarations of incapacity or prohibition [2], [3]. In discourses ranging from philosophical treatises [4] to lively narrative dialogue [5], can shapes both characters’ voices and the narrative’s logic, imbuing language with nuances that signal both empowerment and limitation.
