-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).

-ndur
friend
-ndur (also -dur), ending in some names, like Eärendur; as noted by Christopher Tolkien in the Silmarillion Appendix it has much the same meaning as -ndil "friend"; yet -ndur properly means "servant of" (SA:(noun)dil), "as one serves a legitimate master: cf. Q. arandil king's friend, royalist, beside arandur 'king's servant, minister'. But these often coincide: e.g. Sam's relation to Frodo can be viewed either as in status -ndur, in spirit -ndil." (Letters:286)

meldo

meldo

meldë

#meldë noun "friend", feminine (meldenya "my friend" in the Elaine inscription [VT49:40], Tolkien referring to Elaine Griffiths). Compare meldo.

sondo

tilma
noun. point
-ndil (also -dil) ending occurring in many names, like Amandil, Eärendil; it implies devotion or disinterested love and may be translated "friend" (SA:(noun)dil); this ending is "describing the attitude of one to a person, thing, course or occupation to which one is devoted for its own sake" (Letters:386). Compare -ndur. It is unclear whether the names derived with the ending -ndil are necessarily masculine, though we have no certain example of a woman's name in -ndil; the name Vardilmë (q.v.) may suggest that the corresponding feminine ending is -(n)dilmë.
