The word 温暖 is formed by combining two independent characters, each carrying a related sense of heat. The first character, 温 (wēn), conceptually represents lukewarm or mild warmth, often associated with temperature. The second, 暖 (nuǎn), directly signifies warmth, sunshine, or a cozy heat. Together, they are placed side-by-side not to create a grammatical structure but to blend and reinforce a single, enriched idea; the dual repetition visually and semantically amplifies the sensation of a gentle, pervasive, and comforting warmth, making the compound meaning more resonant and complete than either character alone.
