Add to dictionary

semaphore

[ˈsɛm.ə.fɔːr ]

Definition

Context #1 | Noun

communication signaling

A semaphore is a visual signaling system that uses flags, lights, or mechanical devices to convey information over a distance. Historically, it is used in maritime contexts to communicate between ships or between a ship and the shore. The flags are positioned in different arrangements to represent different letters, numbers, or messages. Semaphore systems can also be found in railways to control train movements. Its simplicity and effectiveness make it a crucial tool in situations where other communication forms are unavailable.

Synonyms

flag system, indicator, signal.

Examples of usage

  • The ship used semaphore to signal its arrival.
  • The railway station relied on semaphore signals for directing trains.
  • The scouts employed semaphore flags to send messages.
  • During the fog, the crew communicated with semaphore.
  • The military utilized semaphore for silent communication.

Origin of 'semaphore'

Main points about word origin

  • The word comes from the Greek words 'sema', meaning 'sign', and 'phorein', meaning 'to carry'.
  • It was first used in the early 19th century to describe a method of conveying messages over distances using visible signals.
  • The term has evolved to refer to various signaling systems, especially in naval and railway communication.

The word 'semaphore' derives from the Greek words 'sēma', meaning 'sign', and 'phorein', meaning 'to carry'. The term first came into use in the early 19th century, particularly in the context of visual telecommunications. It was originally associated with optical telegraphy systems that transmitted messages over long distances through the positioning of movable arms or flags. The invention and implementation of semaphore systems played a significant role in maritime navigation and military communications, particularly before the advent of radio. As technology advanced, the term evolved, but the fundamental concept of visual signaling remains intact. Semaphore's practical applications paved the way for modern signaling systems and practices, underlining its importance in the domain of communication.
