ᴱQ. letinwesse n. “constellation” (Category: Star)
A word appearing as ᴱQ. letinwesse “constellation” in the Qenya Lexicon of the 1910s with initial element ᴱQ. le “with” (QL/52), along with ᴱQ. tinwe “star” and the abstract noun suffix ᴱQ. -sse².
Neo-Quenya: Since all these elements survived in later iterations of Quenya with basically the same meanings, I think ᴺQ. letinwessë can be used as-is in Neo-Quenya despite its age.
