Definition
Meaning
An electrically-powered fog signal, historically used as a maritime navigational aid to warn ships of hazards in conditions of low visibility.
In modern contexts, it can occasionally be used generically or metaphorically to refer to any loud, warning signal or voice, especially in nautical or coastal settings.
Linguistics
Semantic Notes
The term is almost exclusively historical and technical. Its use in contemporary English is rare, typically found in historical texts, maritime museums, or specialist discussions about obsolete navigational technology. It belongs to the same semantic field as 'foghorn', 'siren', and 'bell buoy'.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. The term is equally obscure in both varieties.
