Another name for the Lindar appearing in name lists and The Etymologies from the 1930s (LR/403, Ety/TĀ). It seems to be a combination of tar- “high” and the plural of Qende “Elf”.

Elements
Word Gloss tar- “high, high; [ᴹQ.] king or queen (in compounds)” Elda “Elf, (lit.) one of the Star-folk”
A term for the “Elves who were in or who ever had dwelt in Aman” (MR/349). As such, it was equivalent to the (less arrogant sounding) term Amanyar. This name is a compound of tar- “high” and the plural of Elda “Elf”. This name appeared in The Silmarillion index (SI/Eldar) but not in The Silmarillion itself, though the English term “High Elves” appeared frequently in Tolkien’s writing.
