Quenya
malinornë
noun. mallorn, (lit.) golden/yellow tree
malinornë
yellow-tree
The usual Quenya name for the mallorn tree, most notably appearing in the Entish phrase Laurelindórenan lindelorendor malinornélion ornemalin (LotR/467; Let/448). It is a combination of malina “yellow, golden colour” and ornë “tree”. In one place Tolkien considered an alternate form maldorne where the initial element was instead derived from primitive ✶malnā with ancient *ln* becoming *ld* (PE17/51).
