A noun appearing as ᴱN. cig “cud” in Early Noldorin Word-lists of the 1920s derived from primitive ᴱ✶kiwka and with cognate ᴱQ. tyúka (PE13/140).

Neo-Sindarin: For purposes of Neo-Quenya I use ᴺQ. tyuxë [tyukse] “cud” based on earlier ᴱQ. tyus (tyuks-) from Qenya Lexicon of the 1910s (QL/50) to avoid conflict with later ᴹQ. tiuko “thigh” (Ety/TIW). Therefore I’d use ᴺS. toch “cud” as its equivalent for purposes of Neo-Sindarin.
