Etymology

Verdi Lake in the Ruby Mountains of Nevada

The word is derived from the Old Norse word tjörn meaning pond. Its more specific use as a mountain lake emerges as it is the commonly used term for all ponds in the upland areas of Northern England. Here, it retains a broader use, referring to any small lake or pond, regardless of its location and origin (e.g. Talkin Tarn).[2]

In Scandinavian languages, a tjern or tjärn, tärn or tjørn is a small natural lake, often in a forest or with vegetation closely surrounding it or growing into the tarn.
