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.

taras

noun. mount, hill

A noun appearing in the Quenya Verbal System (QVS) from 1948, with its singular form taras glossed “mount” (PE22/126) and its plural form tarassi glossed “hills” (PE22/126). It appears to be an elaboration of ᴹQ. tára “high”, so perhaps more literally means “✱heights”. In later writings it seems Q. taras was used as a word for “tower” (PE17/22), though S. Taras did reappear as the name of a mountain in Sindarin (S/119).

A sentence appearing in the Quenya Verbal System (QVS) of 1948 as an example of the use of ᴹQ. thar-. In this sentence, Mindolluin might be Quenya rather than Noldorin/Sindarin, perhaps mindon + luine “Blue Tower”; compare Helluin and menelluin.
