A message that is sent quickly over long distances using a special type of wire called a submarine cable.
The company received a cablegram with important news from overseas.
Cablegram → It is formed from "cable" (from Latin *capulum*, meaning a rope or cord) and "-gram" (from Greek *gramma*, meaning something written). The word "cablegram" refers to a message sent via a cable, typically a telegram sent over a telegraph cable.
Think of a 'cable' as a 'rope' that carries a 'written message' ('-gram') — that's why a cablegram is a message sent through a cable.
