What does frogman mean?
A frogman is a person trained and equipped to work underwater, usually wearing a watertight diving suit and self-contained breathing apparatus. The name evokes the image of a suited swimmer gliding through water like an amphibian, and the term is strongly associated with military and professional diving: naval frogmen clear mines and sabotage enemy vessels, while police frogmen search rivers and harbours for evidence or missing persons. It rose to prominence during the Second World War, when elite units such as Italian and British combat swimmers carried out daring underwater operations, and it has since become the standard label for such personnel in English-speaking navies. Because of these associations, 'frogman' conveys skill, stealth, and courage rather than casual recreation; recreational divers are more commonly called simply 'divers' or 'scuba divers'. The plural form is 'frogmen', making the word a familiar example of an irregular-sounding but regular '-man' compound plural.

Like other '-man' compounds (e.g. firemen, gentlemen), frogman forms its plural by changing the final element to '-men'; 'frogsman' is not used.

The word 'frogman' was reportedly coined during World War II, when elite divers in rubber suits gliding unseen through enemy waters reminded observers of frogs.

Etymology of frogman
Frogman is a twentieth-century English compound formed straightforwardly from 'frog' and 'man', coined to describe divers whose rubber-suited, finned appearance suggested the amphibian. The term became widely current during and after the Second World War, when military combat-swimmer units entered public awareness. Its '-man' construction follows a long English pattern seen in words like 'fireman' and 'fisherman', and its plural follows the regular compound rule of inflecting the final element, giving 'frogmen'.
