Okay, one left.
I think "Everlasting, circularly?" might mean a synonym of "everlasting" anagrammed. Then the word ends with UR.
Slight problem... the only words on Encyclopedia of Arda or Tolkien Gateway that fit the E...UR model are names (Earendur, Earnur, and Elendur). Eldamo adds the location-name Eneadur, but that's it.
I suppose 'ah, you, they call back' could be something like -UARE? But the only word ending with that is 'quáre', 'fist' in Quenya; not helpful.
I've finally remembered the existence of the Three Prayers of Numenor, which all start with E and have an RU in them (though not reversed); but none of them seem to fit either.
