S. eryn n. “wood, forest (of trees)” (Category: Woods, Forest)
A word for a wood or forest of trees, most notably in the name Eryn Lasgalen “Wood of Greenleaves”, the name of Mirkwood when it was restored after the War of the Ring (LotR/1094, Let/382).
Possible Etymology: Tolkien gave a couple different explanations for this word. Sometimes he explained it as derived from ✶oronī, an ancient variant plural of S. orn reinterpreted a collective word, much like English “woods” (PE17/33, 153). But elsewhere he said it was derived from an ancient abstract noun ✶oronyē “of trees” (PE17/119). Of the two, I prefer the first explanation as a nice parallel to English.
