saur

adjective. bad (of food), putrid

An adjective meaning “bad (of food), putrid” in Definitive Linguistic Notes (DLN) from 1959 based on the root √SAWA “disgusting, foul, vile” that was the basis of the (Quenya) name Sauron (PE17/183). In a marginal note Tolkien said “No. THAW-, cruel. Saura, cruel”, apparently rejecting this etymology, but then he wrote an “X” next to the marginal note (PE17/184).

Conceptual Development: The Etymologies of the 1930s had N. thaw “corrupt, rotten” under the root ᴹ√THUS, also connected to the name Sauron (Ety/THUS).

Neo-Sindarin: For purpose of Neo-Sindarin, I think saur “putrid” and thaw “corrupt” can coexist.

Gnomish

saur

noun. hound, wild dog

The word G. saur “hound, wild dog” appeared in the Gnomish Lexicon of the 1910s (GL/67), probably a cognate of ᴱQ. savar “wild dog, jackal” under the early root ᴱ√SAẆA (QL/82).

Neo-Sindarin: For purposes of Neo-Sindarin, I’d update this word to ᴺS. huar “wild dog” using the later root ᴹ√KHUG that seems to have replaced ᴱ√SAẆA (Ety/KHUGAN); compare to ᴺQ. huar of similar meaning.
