Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
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.
