Writers employ the term “nudge” to convey more than a mere physical prod—it often embodies a subtle social cue or emotional signal that steers interactions and advances plot without a word being said. A gentle elbow bump might encourage someone to take action, much like the urging push in “[1],” while a familiar, affectionate tap, as seen in “[2],” imbues relationships with warmth and intimacy. At times, the nudge becomes a discreet emblem of responsibility or gentle reproach, as when it signals an impending shift in conversation or behavior in works by Dickens and Dumas ([3], [4]). Even in passages addressing decorum and etiquette, the nudge serves as an understated gesture that encapsulates a wealth of unspoken meaning ([5], [6]).
