What does telegraphy mean?
Telegraphy is the transmission of coded messages over long distances by means of electrical signals. In its best-known historical form, messages were encoded as pulses sent through wires, allowing news, instructions, and commercial information to travel far faster than physical transport. Telegraphy also developed in wireless forms that contributed to early radio communication. The term can refer both to the underlying communication technology and to the practice of operating a telegraph system. Its development had major effects on journalism, diplomacy, transportation, military communication, and commerce, and it is remembered as a predecessor of modern electronic messaging. Although the word is now chiefly historical or specialist, it remains relevant in the history of technology and in discussions of telecommunications. “Telegraph” names an individual device or network, while a “telegram” is a message sent through one.
nounThe transmission of coded messages over long distances, especially by electrical signals through wires; by extension, the system or practice of such communication.
- The transmission of messages over distance using coded electrical signals, especially through wired systems; also, the practice or technology of such transmission.
"The spread of telegraphy transformed commerce and news reporting across Europe and North America."
"Operators received news by telegraphy long before it appeared in the printed newspapers."
"The course examines the rise of wireless telegraphy and its role in early radio communication."

"The museum compares the telegraphies developed by rival nineteenth-century industrialists."
Before email, telegraphy turned electrical pulses into a global network for sending news faster than a horse could carry it.

Where does telegraphy come from?
Telegraphy was formed in English during the nineteenth century from “telegraph” and the noun-forming suffix “-y.” “Telegraph” combines the Greek roots tēle, meaning “far,” and graphein, meaning “to write,” reflecting the idea of writing across a distance. Related English forms include “telegraphic,” “telegraphist,” and “telegram,” all belonging to the same developing technological vocabulary.
How telegraphy is actually used
The term is now chiefly historical or specialist. Modern telephone, email, and digital data systems are not normally described as telegraphy, although modern telecommunications retain some technical and historical links to it.
Easily confused with telegraphy
Telegraphy is the communication system or practice, whereas a telegraph is the device used to transmit signals.
