Quenya
yávien
feminine name. Yávien
yávië
autumn
yávië
noun. autumn, harvest [time or act]
A word translated “autumn, harvest” in The Lord of the Rings appendices (LotR/1111), clearly based on yávë “fruit”. This word referred to the third out of six “official” Elvish seasons in the Calendar of Imladris (LotR/1107), but could also be used more causally for the autumn time of the year (LotR/1111). Given its second gloss “harvest”, I think it can also refer to the time or act of harvesting of crops. However, for the harvest itself (the produce) I would instead use [ᴺQ.] salcessë.
Conceptual Development: The Qenya Lexicon of the 1910s had ᴱQ. Yāvan “(Autumn), Harvest” based on ᴱQ. yāva “fruit, produce” (QL/105). The English-Qenya Dictionary of the 1920s also had ᴱQ. yávan “autumn, harvest”, but in that document the word was deleted (QL/69).

enderi
collective name. middle-days
The name used for leap-days added to the various calendar systems of Middle-earth (LotR/1108, 1112). It is a compound of endë “middle” and the suffixal form -re of ré “day”: ✱enderë “middle-day” pluralized to enderi.
Conceptual Development: In the 1st edition of The Lord of the Rings, a similar term atendëa was used.
First child of Nolondil, known only from a genealogy chart on UT/210. Her name seems to be a compound of yávë “fruit” and the feminine suffix -ien. This name sometimes appeared as Yávië (UT/9).
