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.
A root appearing in the Qenya Lexicon of the 1910s as ᴱ√KANGA “weave” with various derivatives of similar meaning (QL/45), but the actual root probably had medial Ŋ as with ᴱ√KAŊA “twine” appearing later in that same document (QL/98). There are a number of probably-related forms in the contemporaneous Gnomish Lexicon starting with either cang- or cing-, such as G. cang “tangled”, G. cingra “plaited”, and G. cing(win) “spider” (GL/25-26). There are no signs of this root in Tolkien’s later writing, but I think it is worth positing a Neo-Eldarin root ᴺ√KANGA “tangle” to salvage various Gnomish words having to do with tangles and confusion.
