amon obel

place name. Amon Obel

The hill on which Ephel Brandir was built (S/216). The first element is amon “hill”, but the meaning of the second element is unclear. It might be a lenited form ’obel of gobel “walled house or village, town”, but in Tolkien’s later writings, nouns were not usually lenited in this position. A likelier explanation is that the second element might be the Halathian word obel “town”.
