Earlier names for S. Orophin in Lord of the Rings drafts from the 1940s (TI/240). The meaning of this name is unclear.
rhimdad
place name. Rushdown
A river on the other side of the Misty Mountains from the river Hoarwell (S. Mitheithel). It appeared in The Etymologies as N. Rhimdath < Rhibdath (Ety/RIP), and also appeared as Rhimdath on a very early map of the wilderlands (RS/205). In a later draft map it was labeled Rhimdad (TI/296), but was unlabeled in the maps published in The Lord of the Rings.
According to The Etymologies, its initial element is derived from N. rhib- “to flow like a (?torrent)”, apparently assimilated to Rhim-. Its final element is most likely N. dad “down”. Roman Rausch suggested (EE/1.5) that its earlier form Rhimdath may instead have N. dath as its second element, perhaps with the meaning “steep fall, abyss” (EtyAC/DAT).
If this name was adapted to the phonology of later Sindarin, it might be S. ✱Rimdad.

noun. cold pool or lake (in mountains)
rhimb

rhimma-
verb. to flow like a (?torrent)
Rhimdath
Rhimdath
The first element in Rhimdath is related to Noldorin rhib-, rhimp, rhimmo ("to flow like a [?torrent]"), derived from the stem RIP- ("rush, fly, fling"). Christopher Tolkien stated that the name Rhibdath or Rhimdath, given the meaning "Rushdown", was a hastily scribbled addition at the end of the R-stems. In the index he noted that this name only appeared in the Etymologies but is the river described above.[note 1] As the stem DAT- is glossed as "fall down", it is possible that the second element in Rhimdath is a derivative of this stem.
rhib-
verb. to flow like a (?torrent)
lhîn

lhîn
noun. pool
liniath
noun. pools
ovra-
verb. to abound
ovras
noun. crowd, heap.
A noun in The Etymologies of the 1930s given as N. rhim “cold pool or lake (in mountains)” derived from the root ᴹ√RINGI “cold” (Ety/RINGI). This word is the final element of N. Mithrim “✱Grey Lake” in The Etymologies, but in later writings Tolkien explained this name differently, deriving the name from the Elves that lived around the lake, so it may have been abandoned.
Neo-Sindarin: If adapted to Neo-Sindarin, this word would be ᴺS. rim. Since √RINGI “cold” survived in later writings, this word may still be viable, though it would conflict with S. rim “host, a great number”.
