In literature, “warm” carries a rich duality that spans both the physical and the emotional. It often denotes gentle physical heat—a comforting sensation found in the embrace of sunlight on a crisp morning ([1]), the invitation of a fireside ([2]), or even the promise of revived spirit after cold hardships ([3]). Simultaneously, the term conveys a sense of heartfelt kindness and genuine human connection, as seen when a character’s sincerity or affectionate nature is highlighted ([4], [5], [6]). Whether used to animate the external world with inviting weather and cozy surroundings ([7], [8], [9]) or to deepen the internal landscape of emotion and moral character ([10], [11], [12]), “warm” enriches narrative texture by blending tangible comfort with intangible sociability.
