the Statute of Finwë and Míriel
This name was given to two different women in Tolkien’s legendarium. First, it was the name of the first wife of Finwë, the mother of Fëanor (S/63). She was the first Elf to die a non-violent death, for which she was also called Fíriel “She that Sighed, She that Died” (MR/250). The second woman, Tar-Míriel, was the Quenya name of the queen of Númenor, also known as Ad. Ar-Zimraphel (S/269, UT/224). The first element of this name is almost certainly mírë “jewel”. The second element is the suffix -iel, which either means “-daughter” or is a general feminine suffix.
Conceptual Development: The first name given to the last queen of Númenor was ᴹQ. Istar >> Tar-Ilien (LR/27).
