Definition of the word signaller

The word "signaller" originated in the late 19th century as a military term to describe a person who is responsible for communicating orders and signals using visual or audible signals. The term stems from the verb "signal," which can be traced back to the mid-17th century and is derived from the French "signaler," meaning "to make known" or "to indicate." In the military context, signallers use a variety of methods to send messages, such as flags, semaphore lights, and morse code. The role of signallers has evolved over time in response to advancements in technology, with the arrival of radio and telecommunications transforming the way military communications are transmitted today. Nonetheless, the fundamental concept of signalling as a method of transmitting messages in a visual or audible form remains a crucial aspect of military strategy and has also been adopted in various civilian contexts, such as transportation and emergency services.
