The adjective "leering" is often used in literature to evoke a sense of sinister, lascivious, or mocking scrutiny. Its usage frequently imbues a character or even an inanimate quality with a disquieting, predatory aura, suggesting a gaze that is both calculating and morally suspect. In some works, such as Joyce’s Ulysses [1] and Wilde’s The Picture of Dorian Gray [2][3], the term accentuates characters’ dubious intentions and unsettles the reader, while in other narratives it underscores the corrupt or even grotesque ambience by describing faces that leer with malevolence or insolence, as seen in Crane’s portrayals [4][5]. This multifaceted application highlights the word’s power to transform mere observation into a symbol of deeper, often ambiguous, threat.
