A telegram is a type of communication that was popular in the 19th and early 20th centuries. It is a message sent by WIRE or CABLE, usually over long distances. The term 'telegram' is derived from the Greek words tele, meaning 'far away, ' and gramma, meaning 'LETTER.' A telegram is typically composed of a message, which is then dispatched to its intended recipient. This type of communication has largely been replaced by modern forms of communication such as email and text messaging.
