There are more words but they are from Tolkien's earlier conceptional periods. Tolkien likely changed these words as he evolved the aesthetics and completeness of the languages. You may even find languages that Tolkien later rejected. Do not mix words from different time periods unless you are familiar with the phonetic developments.

Qenya 

latimberista

place name. Rivendell

A Quenya name for Imladris(t) (Rivendell) given on a rejected paged of linguistic notes from the 1940s (PE22/127). The elements of this Quenya name are the same as its Noldorin cognate: Tolkien stated that is initial element is latimbe “glen” (√LAT + imbe), and its final element is clearly rista “cut”. On the same page, Tolkien stated that this name was not used in practice, and was replaced the Quenyarized form of the Noldorin name: Imbeláris.

arkimbele

place name. Rivendell

A Quenya name for Imladris(t) (Rivendell) appearing only in the locative form Arkimbelesse “at Rivendell” in linguistic notes from the 1940s (PE22/125). The etymology of the name is unclear, but it may be a combination of arka “narrow” and imbe “dell” as suggested to me by Lokyt in a Discord conversation from 2021-08-25.

imbeláris

place name. Rivendell

A Quenya name for Imladris(t) (Rivendell) given on a rejected page of linguistic notes from the 1940s (PE22/127), simply a Quenyarized form of the Noldorin name.

Below: Tolkien's Late Period (1950–1973). These are from Tolkien's late conceptual period — his most settled forms of the languages. Prefer these over the earlier ones above when composing new text.
