離岸流
riganryū[ɾʲiɡã̠n̺ɾʲɨː]
The Japanese word for riptide is 離岸流 (riganryū).
While 'riptide' is often used in English to describe various strong currents, 離岸流 specifically refers to the rip currents that pull swimmers away from the beach into the ocean.
Meaning: strong tidal flow (noun)
What does it mean word for word?
The term is composed of 離 (leave/separate), 岸 (shore) and 流 (flow), literally meaning a flow that moves away from the shore.
How do you pronounce it?
riganryū
Did you know?
- In Japan, the word 離岸流 is used in public safety warnings, but surfers often use the English loanword リップカレント to describe the same phenomenon.
- While 離岸流 refers to the current itself, the Japanese word for the general phenomenon of the tide coming in and out is 潮汐, which specifically refers to the gravitational pull of the moon and sun.
- The character 岸 used in 離岸流 can be read as kishi when meaning 'shore' but is read as gan in this compound, following a specific pattern of Chinese-derived readings.
