Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
Name for Middle-earth appearing as ambar-endya in notes for Silmarillion drafts from the 1930s (SM/241), and also appearing as Ambarenya in The Etymologies, apparently a compound of Ambar “Earth” and enya “middle” (Ety/MBAR).
