ᴺS. [Ilk.] ?thall adj. “steep, falling steeply (of river)” (Category: Tall)
Ilk. thall adj. “steep, falling steeply (of river)” (Category: to Fall)
An adjective appearing as Ilk. thall “steep, falling steeply (of river)” in The Etymologies of the 1930s, derived from primitive ᴹ✶stalrā and an element in thalos “torrent” (Ety/STAL). The initial [s] spirantalized the following [t] to [θ] (“th”), and the [lr] became [ll], as suggested by Helge Fauskanger (AL-Ilkorin/thall). Since the name Thalos survived in Tolkien’s later writings, presumably thall “steep, falling steeply” became Sindarin after Ilkorin was abandoned.
