Morphology

semaphore + telegraph

Both constituents contribute directly to the compound meaning: 'semaphore' specifies the visual signaling method and 'telegraph' denotes a message-sending system, so a B1 learner who knows both words can infer a telegraph that uses semaphore towers. The noun–noun composition is regular in English and mirrors similar constructions in other languages, making the meaning compositional and easily derivable.

Etymology

Semaphore telegraph comes from old towers with large movable arms or shutters that could be placed in different positions to make simple signals. Watchers at the next tower would read the positions as a message, so the name came to mean 'a system for sending messages by sight'.
