The word 热爱 is formed through a conceptual fusion where the first character 热 (rè), meaning "heat" or "ardent", acts not as a separate idea but as a direct and vivid intensifier for the second character 爱 (ài), meaning "love". It visually and emotionally translates the abstract notion of "love" into the more tangible and forceful concept of "ardent love" or "passionate devotion", as if the warmth and energy of heat are being metaphorically poured into the feeling itself to amplify its depth and fervor.
