In literature, "simper" is used to signify a self-conscious, often ingratiating smile that carries subtle hints of irony, vanity, or suppressed emotion. Characters may employ a simper to mask deeper feelings—as when a slight simper hints at jealousy ([1]) or when an "exquisite simper" betrays vanity ([2]). At other times, authors use the term to illustrate a fleeting expression that reveals complex inner attitudes, such as the deliberate effort to suppress a knowing smile ([3]) or to add a layer of gentle mockery in dialogue ([4]). This versatile term thus enriches character portrayals, subtly communicating their emotions and social nuances without a word.
