noun. tree
The basic Sindarin word for “tree” (LotR/1113), derived from primitive ✶galadā and very well attested. This word dates back at least to The Etymologies of the 1930s, where N. galadh “tree” appeared under the root ᴹ√GALAD (Ety/GALAD). See also orn “(tall) tree” of similar meaning.
Conceptual Development: Gnomish of the 1910s had some earlier version of this “tree” word: G. galdon >> alwen “tree” in the Name-list to the Fall of Gondolin (PE15/24) and archaic/poetic G. †alwen “tree” in the Gnomish Lexicon of the 1910s (GL/19), the latter probably from the early root ᴱ√ALA “spread” that was the basis for ᴱQ. alda “tree” (QL/29).
