A noun in The Etymologies of the 1930s glossed “fat, riches” derived from the root ᴹ√LAR “rich, fat” (EtyAC/LAR). In their Addenda and Corrigenda to the Etymologies, Carl Hostetter and Patrick Wynne suggest that the gloss “riches” was perhaps intended to be “richness” since another word ᴹQ. larma in the same entry was originally glossed “fat, richness” before being revised to “(pig?)-fat, flesh”.

Conceptual Development: When this entry was first written, the root forms were ᴹ√LAR/LAS and the gloss of lar was “Fortune (good), prosperity, Bliss” (EtyAC/LAR). When Tolkien updated this root to be “fat, rich” he seems to have restored the early root ᴱ√LARA from the Qenya Lexicon of the 1910s whose derivatives also had to do with “fat” (QL/51).

Neo-Quenya: For purposes of Neo-Quenya, I would use this word to refer to fat (fattiness) or richness in the taste of food as in “the richness (lar) of the soup”. I would use ᴹQ. larma to refer to specific piece of fat within flesh as in “cut the fat (larma) from the meat”.
