Word Origin & Etymology

Borrowed in the late 18th century from French télégraphe, which was coined by French diplomat Claude Miot de Mélito from Ancient Greek tele- ('far off') and graphein ('to write'). It originally referred to the optical semaphore signaling system invented by Claude Chappe before being applied to Samuel Morse's electrical system.
