yávan noun "harvest, autumn" (LT1:273; in LotR-style Quenya yávië)
Quenya
yávië
noun. autumn, harvest [time or act]
yávan
harvest, autumn
cermië
noun. harvest
cirihta-
verb. to reap, harvest
A neologism for “to reap” or “to harvest” coined by Helge Fauskanger for his NQNT (NQNT) based on ᴹ✶k’rikta- “reap” from The Etymologies of the 1930s (Ety/KIRIK). Petri Tikka instead suggested ᴺQ. cer- “to reap” in PPQ (PPQ) from the early 2000s inspired by Cermië “July” assuming that word also means “✱harvest”, but that seems rather unlikely to me.
salcessë
noun. harvest [product], *produce
yávië
autumn
yávië noun "autumn" (SA:yávë); "autumn, harvest", in the calendar of Imladris a precisely defined period of 54 days, but also used without any exact definition (Appendix D). Noun yáviérë *"Autumn-day", a day outside the months in the Steward's Reckoning, inserted between Yavannië and Narquelië (September and October) (Appendix D)
salcima
adjective. ready for cutting, *harvestable
Endien
autumn
Endien noun, alternative term for "autumn" (PM:135). In the Etymologies, the word Endien was assigned a quite different meaning: "Midyear, Midyear week", in the calendar of Valinor a week outside the months, between the sixth and seventh months, dedicated to the Trees; also called Aldalemnar (YEN, LEP/LEPEN/LEPEK)
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).
