This root first appeared in the Qenya Lexicon of the 1910s as ᴱ√TYURU “curdle”, with derivatives like ᴱQ. tyuru- “curdle” and ᴱQ. tyur “cheese” (QL/50). Derivatives also appeared in the contemporaneous Gnomish Lexicon such as G. cur- “curdle” and G. cûr “cheese” (GL/28). In Gnomish Lexicon Slips revising this document, “cheese” became cír derived from ᴱ√kyus (PE13/111) and Noldorin Word-lists from the 1920s had ᴱN. cír “sour, curdled” and ᴱN. cirtha- “to turn sour” from ᴱ√kyúr (PE13/140).
Neo-Eldarin: For purposes of Neo-Eldarin, I think it is worth positing a root ᴺ√KYUR “curdle” to preserve these early “cheese” words.
