leben (“five”) + nîn (pl. of nen “lesser river”)
Sindarin
Lebennin
place name. Lebennin
Lebennin
noun. five rivers
lebennin
place name. Five Rivers
A region in Gondor with five rivers flowing through into it (LotR/750), translated “Five Rivers” (RC/274), a combination of leben “five” (PE17/95) and the plural nin of nen “water”.
Conceptual Development: When first mentioned in maps for the Lord of the Rings drafts from the 1940s, this name was translated “Seven Streams” even though it appeared as N. Lebennin (TI/311). Later Tolkien eliminated two of the rivers, making the geography consistent with the name.
