telecommunications
⚡📡 electric + news = telecommunications
电 means electric/electricity, 讯 means news or message. Together they literally say electric message — which is exactly what a telegraph or telecommunication is.
电 — rain 雨 + lightning tail 电
Originally a pictograph of lightning streaking from a cloud, written 電 with the rain radical 雨 on top. The bottom 电 depicts the zigzag flash itself. The simplified form 电 drops 雨 and keeps just the lightning shape. Meaning extended from 'lightning' to 'electricity' in modern usage.
