The word 感觉 is formed by combining two characters, each contributing a layer of meaning that merges into a single, unified concept. The first character, 感, fundamentally relates to "sensing" or "feeling", as in physical touch or emotional impression. The second, 觉, conveys "awareness", "consciousness", or "realization". When fused, they create a concept where raw sensory or emotional input (感) meets conscious perception and understanding (觉), resulting in the integrated idea of "feeling" or "sensation" as something both experienced and recognized.
