The word profound is used in literature to evoke a sense of great depth and intensity in both tangible and intangible realms. Authors apply it to describe physical attributes—a gaze filled with deep mystery ([1]), an enveloping silence that charges a scene with tragic importance ([2], [3]), or even the quiet fold of slumber ([4], [5])—while also extending its meaning to internal states such as earnest admiration ([6]), reflective melancholy ([7]), or intellectual depth and gravitas ([8], [9]). In this way, profound becomes a versatile descriptor that encapsulates both the measurable and the ineffable, enriching character portrayals and setting powerful emotional tones throughout literary works.
