The basic Quenya word for “tree” (LotR/1113), derived from primitive ✶galadā and very well attested. This word dates all the way back to the Qenya Lexicon of the 1910s where ᴱQ. alda “tree” appeared under the early root ᴱ√ALA “spread” (QL/29). Tolkien seems to have switched its derivation to ✱galadā in The Etymologies of the 1930s, where ᴹQ. alda “tree” appeared under the root ᴹ√GALAD of the same meaning (Ety/GALAD). See also ornë “(tall) tree” for a discussion of another similar word.
Conceptual Development: There were a few instances where the word alda had a different meaning. In Early Qenya Word-lists of the 1920s, alda was glossed “branch” (PE16/139). In notes from 1959 Tolkien said “✱galadā, originally only large flourishing plant, as tree, and especially one that flowered, Q alda, S galað; the general word for ‘tree’ was Q orne ‘upstanding plant’ (PE17/153)”. But in its numerous appearance elsewhere, alda was simply a general word for “tree”.
