🥅 罩 = net radical 罒 on top + 卓 zhuó; a net dropped on top to cover or trap
罩 — net 罒 (top) + zhuō 卓 (phonetic)
A semantic-phonetic compound. The top component 罒 is the 'net' radical, signaling the meaning of something that covers or traps, while 卓 supplies the sound (zhuō → zhào). The original sense was a bamboo fish trap or cover, which broadened to mean 'to cover, cover over,' as in a lampshade or fume hood.
