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.
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.
An unglossed root in the Qenya Lexicon of the 1910s, previously given as [deleted] ᴱ√TAŘA “chevaux de frise” (a fortification of wooden spikes), with derivatives like ᴱQ. tanda “hedge, fence, enclosure; border, rim”, ᴱQ. tarasse “hawthorn”, and ᴱQ. tarwa “garden, enclosure” (QL/87, 89). It also had derivatives in the contemporaneous Gnomish Lexicon such as G. tadhos “hawthorn”, G. tand “enclosure, garden”, and G. tath “hedge, fence” (GL/68). I think it is worth positing a Neo-Root ᴺ√TAD “enclosure” to salvage some of these early words.
