Key facts
- Several large lakes in Mongolia are named using a word that translates to 'sea' or 'ocean.'
- The Mongolian word 'dalai' historically meant a vast expanse of water, not exclusively oceans.
- This linguistic convention led to lakes being called 'seas' despite being inland.
- Lake Khuvsgul is also known as 'Khövsgöl Sea' due to its immense size.
- The term 'dalai' also means 'ocean' in the title 'Dalai Lama.'
Several of Mongolia's largest lakes carry the word "sea" in their names, a distinction that may seem puzzling given the country’s landlocked location. The likely explanation lies in the Mongolian language itself, where the word далай (dalai) has historically been used more broadly to describe a vast expanse of water, rather than being reserved exclusively for oceans.
This linguistic tradition is believed to have influenced the naming of some of Mongolia’s most prominent lakes. While the country has a distinct word for lake, "нуур" (nuur), some large bodies of water are also referred to using "dalai." For instance, Lake Khuvsgul, one of Mongolia's largest freshwater lakes, is known locally as "Khövsgöl Nuur" but also as "Khövsgöl Dalai," or "Khövsgöl Sea," reflecting its immense size.
The broader meaning of "dalai" is not unique to lake names and also appears in the title "Dalai Lama," which is often interpreted as "Ocean of Wisdom." In 1578, the Mongol ruler Altan Khan conferred this title on the Tibetan Buddhist leader Sonam Gyatso.
Scholars acknowledge that while the use of "dalai" for certain lakes is documented, the exact origin of this naming convention is not definitively concluded. However, the historical understanding of "dalai" as a term for a vast body of water, rather than solely oceans, explains why these inland lakes acquired such names.
