Definition
Meaning
A military or civilian organization responsible for maritime safety, security, and law enforcement in coastal waters.
The term can refer to the organization itself, its personnel, or individual members. In some contexts, it can imply a protective, vigilant presence at sea, analogous to a police force for coastal regions.
Linguistics
Semantic Notes
The term is a compound noun, often functioning as an open compound (coast guard) but can be hyphenated (coast-guard) when used as a modifier (e.g., coast-guard vessel). It is usually treated as a singular collective noun when referring to the organization ("The coast guard is searching") but plural when referring to its members ("The coast guard were deployed").
