Elendil masc. name"Star-friend", "Lover or student of stars", applied to those devoted to astronomical lore. However, when the Edain used this name they intended it to mean "Elf-friend", confusing elen "star" and elda "elf" (WJ:410). (This idea that the name was misapplied seems to be late; Tolken earlier interpreted the name as an ancient compound Eled + ndil so that the meaning really was "Elf-friend"; see Letters:386. See also NIL/NDIL in the Etymologies, where Elendil is equated with "Ælfwine", Elf-friend.) Allative Elendilenna "to Elendil" (PM:401); Elendil Vorondo genitive of Elendil Voronda "Elendil the Steadfast" _(CO) Pl. Elendili the Númenórean Elf-friends (Silm)_; the variant Elendilli in SD:403 would seem to presuppose a stem-form Elendill- not attested elsewhere. Tar-Elendil a Númenorean king, UT:210.

Quendendil (also contracted Quendil; pl. Quendili in WJ:410) masc. name "Elf-friend" (WJ:410)
-dil, -ndil, ending that Tolkien likened to Old English "-wine", sc. "-friend" as part of names, e.g. Elendil, Eärendil (NIL/NDIL); see the entry -ndil. Also long -dildo (VT46:4), and possibly -(n)dilmë as the corresponding feminine form (see Vardilmë).
-nil, final element in compounds, similar in meaning to Old English "-wine", sc. "-friend" as an element in names (NIL/NDIL). Also long -nildo (VT46:4). Variant of -ndil. In Eärnil, contraction of Earendil.
Elessar masc. name "Elf-stone" (Elen + sar, actually "Star-stone", cf. Elendil concerning elen "star" being used to mean "Elf") (LotR3:V ch. 8). Genitive Elesarno _(VT49:28, read _Elessarno?) indicates that the stem is -sarn-. As a common noun, elessar or "elf-stone" may signify "beryl" (in the chapter Flight to the Ford in the LotR, Aragorn finds "a single pale-green jewel" and declares: "It is a beryl, an elf-stone"). Elessar as a name may also be seen as a pun or variant of Elesser "Elf-friend".
Devoted to the Stars
Elendil's name actually means "Devoted to the Stars" in Quenya.
For the Dúnedain it was intended to signify "Elf-friend" (Adûnaic Nimruzîr), since they tended to confuse the Quenya element EL for both "Elf" and "star".
