Detta förklaras i JRR Tolkiens brev # 211 till en Mrs Beare.
Q. What is the meaning of this invocation, and of Frodo’s words in the previous chapter, ‘Aiya Eärendil Elenion Ancalima!’?
A. Before 1914 I wrote a ‘poem’ upon Earendel who launched his ship like a bright spark from the havens of the Sun. I adopted him into my mythology – in which he became a prime figure as a mariner, and eventually as a herald star, and a sign of hope to men. Aiya Eärendil Elenion Ancalima (II 329) ‘hail Earendil brightest of Stars’ is derived at long remove from Éala Éarendel engla beorhtast.

Before 1914 I wrote a ‘poem’ upon Earendel who launched his ship like a bright spark from the havens of the Sun. I adopted him into my mythology – in which he became a prime figure as a mariner, and eventually as a herald star, and a sign of hope to men. Aiya Eärendil Elenion Ancalima (II 329) ‘hail Earendil brightest of Stars’ is derived at long remove from Éala Éarendel engla beorhtast. But the name could not be adopted just like that: it had to be accommodated to the Elvish linguistic situation, at the same time as a place for this person was made in legend. From this, far back in the history of ‘Elvish’, which was beginning, after many tentative starts in boyhood, to take definite shape at the time of the name’s adoption, arose eventually (a) the C.E. stem ^AYAR ‘Sea’fn117, primarily applied to the Great Sea of the West, lying between Middle-earth, and Aman the Blessed Realm of the Valar; and (b) the element, or verbal base (N)DIL, ‘to love, be devoted to’ – describing the attitude of one to a person, thing, course or occupation to which one is devoted for its own sake.fn118 Earendil became a character in the earliest written (1916–17) of the major legends: The Fall of Gondolin, the greatest of the Pereldar ‘Half-elven’, son of Tuor of the most renowned House of the Edain, and Idril daughter of the King of Gondolin. Tuor had been visited by Ulmo one of the greatest Valar, the lord of seas and waters, and sent by him to Gondolin. The visitation had set in Tuor’s heart an insatiable sea-longing, hence the choice of name for his son, to whom this longing was transmitted. For the linking of this legend with the other major legends: the making of the Silmarils by Fëanor, their seizure by Morgoth, and the recapture of one only from his crown by Beren and Lúthien, and the coming of this into Earendil’s possession so that his voyages westward were at last successful, see I 204–6 and 246–249. (The attempt of Eärendil to cross Ëar was against the Ban of the Valar prohibiting all Men to attempt to set foot on Aman, and against the later special ban prohibiting the Exiled Elves, followers of the rebellious Fëanor, from return: referred to in Galadriel’s lament. The Valar listened to the pleading of Eärendil on behalf of Elves and Men (both his kin), and sent a great host to their aid. Morgoth was overthrown and extruded from the World (the physical universe). The Exiles were allowed to return – save for a few chief actors in the rebellion of whom at the time of the L.R. only Galadriel remained.fn119 But Eärendil, being in part descended from Men, was not allowed to set foot on Earth again, and became a Star shining with the light of the Silmaril, which contained the last remnant of the unsullied light of Paradise, given by the Two Trees before their defilement and slaying by Morgoth. These legends are deliberately touched on in Vol. I as being the chief ones in the background of The L.R., dealing with the relations of Elves and Men and Valar (the angelic Guardians) and therefore the chief backward links if (as I then hoped) the Silmarillion was published.
I relate these things because I hope they may interest you, and at the same time reveal how closely linked is linguistic invention and legendary growth and construction. And also possibly convince you that looking around for more or less similar words or names is not in fact very useful even as a source of sounds, and not at all as an explanation of inner meanings and significances. The borrowing, when it occurs (not often) is simply of sounds that are then integrated in a new construction; and only in one case Eärendil will reference to its source cast any light on the legends or their ‘meaning’ – and even in this case the light is little. The use of éarendel in A-S Christian symbolism as the herald of the rise of the true Sun in Christ is completely alien to my use. The Fall of Man is in the past and off stage; the Redemption of Man in the far future. We are in a time when the One God, Eru, is known to exist by the wise, but is not approachable save by or through the Valar, though He is still remembered in (unspoken) prayer by those of Númenórean descent.
