About
The character 密 is a phono-semantic compound: the semantic component 山 'mountain' points to the original setting, while 宓 (mì) provides the sound. Originally, it denoted a secluded, sheltered place deep in the mountains. Over time, the sense of tight enclosure expanded to describe anything closely packed, dense forests, thick fog, crowded spaces. Eventually, this physical density took on figurative dimensions, yielding the modern meanings of 'secret,' 'confidential,' and 'intimate', all rooted in the idea of something kept close or hidden away.
