  • underwater swimmer

Usage Note

Frequently used with a preceding noun to specify the type of diver (e.g., scuba diver, rescue diver, commercial diver, competitive diver). When the context is competitive diving from a board or platform, the word diver alone is sufficient, but adding competitive or platform can prevent confusion with the underwater-work sense.

Common Mistakes

The diver jumped into the water without any air tank.' (when meaning a competitive platform diver)
The competitive diver jumped off the board into the pool.
For sport diving from a board, the person is still called a diver; the equipment difference makes the context clear.

Synonym discussion

Sense: noun/1

All three words describe people who go underwater, but the context differs. Scuba diver is the broadest everyday term for someone who uses compressed-air tanks for recreational or scientific diving; it is the most neutral and common in travel and leisure contexts. Frogman is a more informal and narrower term, used mainly for military, police, or tactical divers — you would not call a vacationing scuba diver a frogman. Free diver refers to someone who dives without any breathing equipment, holding their breath instead; this is a distinct sport and skill set. For example: 'The hotel offers scuba diving classes for beginners,' but 'The navy sent a frogman to inspect the ship hull,' and 'Folake can hold her breath for three minutes as a trained free diver.'

Etymology

Old EnglishMiddle EnglishEnglish

The word diver comes from the verb dive, which traces back to the Old English dūfan (meaning 'to dip, plunge, or sink'), combined with the suffix -er (meaning 'a person who does something'). By the early 1600s, diver was used in English to describe someone who plunges into water, and later specifically someone who goes underwater using breathing apparatus.
