A bright float rests on the sea while a fisher returns to the surface. In Jeju, this picture can carry a history of professional women’s work, shared coastal knowledge, harvesting customs and family livelihoods. The women known as haenyeo are not simply a dramatic photograph or a challenge for visitors to imitate.
This country-vocabulary guide offers 100 distinct terms, each with a clear meaning, natural word pairing and original example. It takes readers from marine habitats and documented equipment through cooperatives, oral knowledge, safeguarding and the evidence needed to describe a living practice respectfully. It is not a freediving tutorial. Breath-hold diving is hazardous and requires professional instruction and appropriate safeguards.
The UNESCO Intangible Cultural Heritage entry confirms that the Culture of Jeju Haenyeo was inscribed in 2016. It describes fishing without breathing equipment, a characteristic surfacing sound, different experience levels and knowledge shared through families, schools and cooperatives. UNESCO’s interviews with working haenyeo also emphasise limits, health and changing circumstances; any figures quoted from one woman’s experience are not blanket averages for all divers.

30. Equipment change — A modification in tools or materials over time. Natural pairing: historical equipment change. Original example: A change in flotation materials does not erase the tradition.
Breath-hold work as a documented profession
These terms describe an occupation and documented experience levels. Do not turn descriptions into instructions for breath-hold diving.
31. Breath-hold diving — Entering the water without an underwater breathing-gas supply. Natural pairing: professional breath-hold work. Original example: The documentary records breath-hold work without teaching viewers to attempt it.
32. Resurfacing — Returning to the water surface after being submerged. Natural pairing: observed resurfacing. Original example: The photograph captures a diver just after resurfacing.

Four exercises: observe, compare, attribute
Practice A: Label a documented photograph.
Locate a museum image showing a tewak and mangsari. Explain which is the float and which contains harvested catch. Do not invent the pictured diver’s name or year.
Practice B: Separate an interview from a statistic.
A UNESCO interview includes an experienced diver’s description of sharing catch. Write one sentence about that interview and a separate question about whether all local cooperatives use the same arrangement.
Practice C: Read a species list.
Compare abalone, sea urchins and seaweed. Name their biological categories, then explain why catch totals must specify species, place and reporting period.
Practice D: Write a respectful heritage caption.
Include the woman’s occupation, the Jeju setting, a documented aspect of equipment or cooperation, and the source. Avoid wording that invites untrained visitors to attempt breath-hold diving.

Carry one accurate sentence forward
Describe a haenyeo as a working woman in a documented coastal setting, naming one tool and one community relationship. Then state whether your evidence came from the practitioner, a museum or UNESCO. That is a more useful contribution to cultural understanding than an unsupported claim about how long everyone can stay underwater.
