🐴 马 horse + 主 master: the masters horse stays stationed at its post
zhù sounds like zoo — animals kept in one place. The radical 马 horse plus 主 master suggests a cavalry horse halted at its masters command, standing guard.
驻 — horse 马 + master/host 主
A semantic-phonetic compound. The horse radical 马 gives the meaning, originally referring to halting a horse or stationing it somewhere, while 主 (zhǔ) supplies the sound. From 'halting a horse' it broadened to 'to stop, station, be stationed,' as in troops or diplomats posted at a location.
