What does diver mean?
A diver is someone who plunges into water or swims beneath its surface, whether by holding their breath, using scuba equipment, or descending in a diving suit. The term most often describes people who work or explore underwater — salvage crews, marine biologists, naval personnel, and recreational scuba enthusiasts — but it also names athletes in the sport of diving, who perform acrobatic manoeuvres as they fall from boards or platforms into pools. In British English, 'diver' additionally denotes a large waterbird that hunts fish by swimming submerged, called a loon in North America. The word carries no strong connotation; it is plain, practical vocabulary found everywhere from news reports about shipwreck exploration to coverage of Olympic competition. Its versatility across occupational, sporting, and ornithological contexts makes it a compact example of how English reuses a single agent noun — simply 'one who dives' — across very different domains of human and natural activity.
A person who swims or works underwater, especially using breathing apparatus.
"Commercial divers repaired the pipeline on the seabed."
An athlete who competes in diving, leaping acrobatically from a springboard or platform into water.
"She won gold as the youngest diver at the championships."
A diving waterbird; the British name for the bird known in North America as a loon.
"We heard the haunting call of a great northern diver across the lake."
Regular plural, used when referring to multiple people who dive or, in British usage, multiple diving birds.
"Divers explored the wreck site at dawn."
The word 'diver' covers everyone from pearl hunters of the Persian Gulf to Olympic athletes who leap off ten-metre platforms without ever touching the water.

Etymology of diver
Diver is formed from the verb 'dive' with the agent suffix '-er', literally meaning 'one who dives'. The verb 'dive' descends from Old English 'dīfan', meaning to plunge or sink, a word of Germanic origin that is related to 'dip'. The agent noun arose naturally in Middle and early Modern English as the activity of diving — for pearls, salvage, and later sport — became a recognised pursuit.
