The word 沉默 is formed through the conceptual blending of two distinct ideas into a single, more profound meaning. The first character, 沉 (chén), carries the meaning of sinking, submerging, or something heavy and deep. The second, 默 (mò), means silent or quiet. When combined, they do not simply denote "quiet", but instead create a metaphorical image of silence that has depth, weight, and stillness, like a quiet so profound it feels tangible, as if sinking into a deep, soundless pool. This formation transforms the basic notion of not speaking into an evocative state of profound, intentional quietude.
