Starting in the early 1920s, Tolkien changed the name of language of the Noldoli from Gnomish to (Early) Noldorin. This lexicon use the label ᴱN. to distinguish it from the Noldorin language of Tolkien’s Middle Period (1930-1950). There are enough differences between this version of the language and Gnomish that their entries are group separately. See Noldorin and Sindarin for the developments of this language later in Tolkien’s life.
