A minor river that flowed from beneath the Halifirien to join the Entwash at its outflow into Anduin. It formed part of Rohan's eastern border with Gondor.



Mering comes from the Old English mere, 'boundary', representing a name in the tongue of the Rohirrim, and therefore the name cannot predate the arrival of the Rohirrim in Rohan.

The Elvish name of this stream, Glanhír, has exactly the same meaning, though the relationship between the two names is unclear. It seems most likely that Glanhír was a Gondorian translation of the name chosen by the Rohirrim (as there was no boundary between the two nations before that time). Even before the coming of the Rohirrim, however, the stream had marked an internal boundary between the Gondorian regions of Calenardhon and Anórien, so conceivably Glanhír was an original Sindarin name that was adopted and translated by the Rohirrim.
