A noun appearing as ᴱQ. tyus (tyuks-) “cud” in the Qenya Lexicon of the 1910s derived from the early root ᴱ√TYUKU “chew” (QL/50). It became ᴱQ. tyúka “cud” in Early Noldorin Word-lists of the 1920s as a cognate of ᴱN. cig from primitive ᴱ✶kiwka (PE13/140).
Neo-Quenya: The form tyúka veers too close to later ᴹQ. tiuko “thigh” (Ety/TIW), so I’d instead restore the 1910s form as ᴺQ. tyuxë [tyukse] “cud” derived from the Neo-Root ᴺ√TYUK.
