The word 幽默感 is formed by combining the concept of "humor" (幽默) with the idea of "sense" or "feeling" (感), creating a single, unified notion that refers not just to humor itself, but to the specific human capacity to perceive, appreciate, and embody it. It fuses the abstract quality of wittiness with the innate faculty for experiencing it, resulting in a term that encapsulates the entire phenomenon of one's "sense of humor".
