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.
hilmi
collective noun. family, offspring
soresta
noun. family
The word ᴱQ. soresta “family” appeared in the Qenya Lexicon of the 1910s as a combination of ᴱQ. so- “together” and ᴱQ. resta “kin” (QL/85).
Neo-Quenya: For purposes of Neo-Quenya I would adapt this word as ᴺQ. orendë as a combination of later prefix Q. o- “together” and ᴺQ. rendë “kin”. Furthermore, I would use it specifically for a nuclear family (just the parents and children), as opposed to Q. nossë which seems to refer to an extended family or clan.
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.
The word ᴱQ. hilmi “family, offspring” appeared in the Qenya Lexicon of the 1910s as a derivative of the early root ᴱ√HILI (QL/39). In the contemporaneous Gnomish Lexicon, the word hilmie was given as the Qenya cognate of G. hilm “posterity, one’s descendants, progeny, offspring” (GL/49).
Neo-Quenya: I would adapt this word into Neo-Quenya as singular ᴺQ. hilmë “offspring, ✱descendant”, and use plural hilmi to refer to the entirety of one’s extended family, including all descendants. Among the Elves, the original ancestor would still be alive and able to interact with their descendants of all generations, so this would be a living rather than historical relationship.
