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.
tolla
noun. hill top
tolda
noun. hill (with a flat top), hill top; town on a hill

tolome

A noun in the Qenya Lexicon of the 1910s glossed “island”, a more elaborate form of ᴱQ. tol of similar meaning (QL/94). It also appeared as tolome “island” in the Poetic and Mythological Words of Eldarissa (PME/94).
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.
A noun in the Qenya Lexicon of the 1910s glossed “hill with a flat top, town on a hill” derived from the root ᴱ√TOLO (QL/94). It also appeared in the Poetic and Mythological Words of Eldarissa with the glosses “flat hill, town on hill” (PME/94). It appeared in the modified form tolla with the sense “hill top” in various versions of the ᴱQ. Oilima Markirya poem, mostly in various inflected forms (PE16/75; MC/214, 221). There is no sign of this word thereafter.
