ᴹ√LAR root. “rich, fat”
A root in The Etymologies of the 1930s glossed “rich, fat” (EtyAC/LAR), a later iteration of the root ᴱ√LARA the Qenya Lexicon of the 1910s which had derivatives like ᴱQ. laru “fat, grease” and ᴱQ. laruke “fat, rich” (QL/51). The 1930s root includes the derivative ᴹQ. larma “[?pig-]fat, flesh” so it likewise seems to refer to fatty flesh and rich food, but in the 1930s it replaced a deleted entry with both ᴹ√LAR and ᴹ√LAS whose derivatives had glosses connected to blessedness (EtyAC/LAR), so it seems Tolkien was vacillating somewhat on the meaning of this root.
