In Sindarin, one of Tolkien's Elvish languages, "Fangorn" is a compound of "fanga", "beard", and "orne", "tree", so it is the equivalent of the English "Treebeard". The Rohirrim (Riders of Rohan) called Fangorn Forest the "Entwood", the wood of the Ents. Treebeard gave it various names in Quenya, another Elvish language: ""Ambaróna"" means "uprising, sunrise, orient" from "amba", "upwards" and "róna", "east". ""Aldalómë"" means "tree twilight" from "alda", "tree" and "lómë", "dusk, twilight". ""Tauremorna"" means "gloomy forest" from "taur", "forest", and "morna", "gloomy". ""Tauremornalómë"" means "gloomy twilight forest".
