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 noun appearing as ᴹQ. veru “husband and wife, married pair” in The Etymologies of the 1930s derived from primitive ᴹ✶besū under the root ᴹ√BES “wed” (Ety/BES). It seems to be an intrinsically dual word. It also appeared as an element in the name ᴹQ. Are Veruen “Day of the Spouses”, but under the entry where this word appeared the form was derived from ᴹ✶Bedū, reflecting a variant (and apparently abandoned) root ᴹ√BED (Ety/LEP).
Conceptual Development: The dual form ᴱQ. veringwi “husband and wife” appeared in the Early Qenya Grammar of the 1920s (PE14/77). The same form appeared in the English-Qenya Dictionary of the same period with the gloss “married pair, husband and wife”, where it was apparently related to the adjective ᴱQ. verin “married” (PE15/75).
Neo-Quenya: ᴹQ. veru “married pair” collides with the later word Q. veru “husband”, so for purposes of Neo-Quenya I would adapt the Early Quenya form as ᴺQ. verinu “married pair” to reflect later Quenya dual formations.
