ᴱN. lhub n. “fat” (Category: Fat, Grease)
A noun appearing as ᴱN. lhub “fat” in Early Noldorin Word-lists of the 1920s (PE13/149). It was a later iteration G. lub “fat, fat flesh” in Gnomish Lexicon of the 1910s derived from primitive ᴱ✶lūpe (GL/55).
Neo-Sindarin: I think it is worth retaining these words for purposes of Neo-Sindarin as ᴺS. lûb “fat, (fat) flesh” from a Neo-Root ᴺ√LUP.
