Ŋópïŋ-Arún

In geographical terms, the Ŋópïŋ-Arún is the confluence (often mislabeled as a fork, sorry!) of a River System. More specifically, it is the point at which two rivers merge together to form a larger stream. The most famous such example of a Ŋópïŋ-Arún is the Ŋópïŋ-Arún-Khërn, the confluence of the western and eastern rivers of the Kairn River System.

The name refers to a corruption of the word 'No', meaning two, with the antiquated suffix -pïŋ, referring to a multiple thereof. Thus, Ŋópïŋ means 'double'. Arún itself simply means river, so the full name, Ŋópïŋ-Arún, is the Double River, referring to the two segments that come together. The name can be altered for other quantities (Ýópïŋ-Arún is the most common name for three streams converging) but this is a rare occasion in itself.
