About
The word 秘密 is formed by combining two characters: 秘, which is composed of the semantic radical 禾 (grain) and the phonetic component 必 (must), historically associated with hidden matters; and 密, composed of the semantic radical 宀 (roof) and the phonetic component 必 (must), with 山 (mountain) suggesting denseness or closeness. Both characters individually convey notions of concealment, and together they create a compound word where their meanings reinforce each other to denote "secret".
