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 verb in the Qenya Lexicon of the 1910s appearing as ᴱQ. sanga- “pack tight, compress, press” under the early root ᴱ√SAŊA (QL/81). In the Oilima Markirya poem from around 1930, Tolkien used (active participle?) sangane to mean “gather[ing]” (MC/214), perhaps with the sense “✱press together”. In the Declension of Nouns (DN) of the early 1930s Tolkien said the verb element sanga- was the basis for the noun ᴹQ. sanguma “a press” (PE21/8).
Neo-Quenya: In Tolkien’s later writings, he had the roots ᴹ√STAG “press, compress” (Ety/STAG) and √THAG “oppress, crush, press”, so I would assume the more ancient form of the verb sanga- was þanga- to be compatible with these later roots. In a 2026-04-02 post to the Vinyë Lambengolmor Discord Server (VLDS), Luinyelle suggested this word might also mean “contract [linguistically]”.
