Eärendil means 'Lover of the Sea' in Tolkien's invented language of Quenya. However, Tolkien borrowed the name from Old English literature. Tolkien states (Letters, 297) that the name comes from Anglo-Saxon éarendel. He was struck by its "great beauty" c. 1913, which he perceived as
entirely coherent with the normal style of A-S, but euphonic to a peculiar degree in that pleasing but not 'delectable' language.
There is a poem by Tolkien dated to 1914 entitled "The Voyage of Eärendel the Evening Star" (published in The Book of Lost Tales 2 267–269). Tolkien was also aware of the name's Germanic cognates (Old Norse Aurvandill, Lombardic Auriwandalo), and the question why the Anglo-Saxon one rather than the Lombardic or Proto-Germanic form should be taken up in the mythology is alluded to in The Notion Club Papers. The Old Norse together with the Anglo-Saxon evidence point to an astronomical myth, the name referring to a star, or a group of stars, and the Anglo-Saxon in particular points to the morning staras the herald of the rising Sun (in Crist Christianized to refer to John the Baptist).
The first line is paralleled by Frodo Baggins' exclamation in The Two Towers (the line appears in The Return of the King in the Peter Jackson films), Aiya Eärendil Elenion Ancalima! which is Quenya, and translates to "Hail Eärendil, brightest of stars!" Frodo's exclamation was in reference to the 'Star-glass' he carried, which contained the light of Eärendil's star, the Silmaril.
