A word for a “(tall) tree” in Quenya, derived from primitive ✶ornē (Let/426; PE17/25, 50). This word can be compared to the more common alda “tree”. Talking about the primitive forms Tolkien said:
> ... ✱ornē “tree” originally and usually applied to the taller, straighter, and more slender trees, such as birches [as opposed to] ... stouter and more spreading trees, such as oaks and beeches, were called in C.E. galadā “great growth” (NM/349 and note #1).
I would use ornë in Quenya only for tall straight trees, and alda as either the general word for “tree”, or where applicable for broad and spreading trees.
Conceptual Development: The earliest precursor to this word seems to be ᴱQ. orond- “bush”, cognate to G. orn “tree” in the Gnomish Lexicon of the 1910s (GL/62). It became {orne >>} ᴱQ. orme “tree” in Early Qenya Word-lists of the 1920s (PE16/139) and then ᴹQ. orne “high isolated tree” in The Etymologies of the 1930s derived from ᴹ✶ÓR-NI “high tree” (Ety/ÓR-NI). It retained the form orne thereafter.
-tar or tar-, element meaning "king" or "queen" in compounds and names (TĀ/TA3), e.g. Valatar; compare the independent nouns tár, tári. Prefix Tar- especially in the names of the Kings and Queens of Númenor (e.g. Tar-Amandil); see their individual names (like Amandil in this case), cf. also Tar-Mairon "King Excellent", title used by Sauron (PE17:183). Also in Tareldar "High-elves"; see also Tarmenel.
