netizen
🌐 网 wǎng (net/web) + 民 mín (people/citizen) = the web's people, netizens
网 is the same 'net' as in 网络 (network) and 互联网 (internet); 民 means the people or citizens, as in 人民 (the people). Together: citizens of the net.
网 — net radical 冂 + 亡 (phonetic)
網 (simplified 网) originally pictured a hunting or fishing net, with crossed mesh lines inside a frame. The modern simplified form 网 keeps that net shape directly. The traditional 網 adds 糸 (silk thread) for the material and 亡 as a phonetic hint for the wǎng sound.
