Rithil-Anamo place name "Ring of Doom", translation of the foreign word Máhanaxar that was adopted and adapted from Valarin (WJ:401). Compare Anamo, q.v. Presumably *Risil-Anamo in Exilic Quenya, since the digraph th of rithil must represent the spirant þ (expressed by the letter súlë, older thúlë, in Tengwar writing).

ring of doom
A translation of the Valarin name Māχananaškād, more commonly known by its direct adaptation into Quenya: Q. Máhanaxar (WJ/401). The presence of the sound “th” in Rithil-Anamo means this name must be either archaic or from the Vanyarin dialect of Quenya. The name is translated “Doom-ring”, but the etymology of its elements is unclear. The second element may be related to the verb nam- “to judge”, but nothing similar to the first element appears elsewhere in the published material.
