A telegraph message is a form of communication that uses electrical signals to transmit information over a long distance. It is also known as a TELEGRAM, which is an 8-letter word, or a CABLE, which is a 5-letter word. A CABLEGRAM is a 9-letter word and is a combination of the two words, CABLE and TELEGRAM. Telegraph messages are typically sent via a telegraph machine, which is an apparatus that sends and receives electrical signals.
