贮藏
zhù cáng · HSK 7
to store up
📦 贮藏 = 贮 store + 藏 stash-away; both halves mean to keep goods tucked away
贮 is the act of storing, 藏 means to hide or conceal. Doubled up, they reinforce each other: goods deposited and kept out of sight. 藏 cáng sounds a bit like tsahng, the soft hush of something hidden.
藏 — grass radical 艹 + 臧 (phonetic)
A semantic-phonetic compound. The grass radical 艹 on top suggests plants or vegetation used for concealment, while 臧 below provides the sound. Originally meant to hide or conceal something in the grass, later extended to mean 'store' or 'collect,' and when read 'zàng' it means a treasury or storehouse.
