Early Primitive Elvish

Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
mṇgṇ
root. *butter
Derivatives
An unglossed root ᴱ√MṆGṆ appeared in the Qenya Lexicon of the 1910s with derivatives ᴱQ. mange “grease” and ᴱQ. manya “butter” (QL/62). G. mang “butter” from the contemporaneous Gnomish Lexicon is also almost certainly related (GL/56). In Qenya Word-lists from the 1920s Tolkien gave ᴱQ. mingwe “butter” which may be related (PE16/141).
Neo-Eldarin: For purposes of Neo-Eldarin, I think it is worth positing a root ᴺ√MANGYA to salvage early “butter” words.
