Ezellohar
From Tolkien Gateway
Ezellohar (VQ. "Green Mound", pron. [eˈzelːoxar]; ezello = green) was the Green Mound before the western gates of Valmar, also called Corollairë, where the Two Trees of Valinor grew.
Later the Noldor almost certainly would have called this Erellohar (pron. [eˈrelːoxar], TA Exilic [eˈrelːohar])—this form is unattested, but likely because of the natural progression of Noldorin Quenya sound laws that followed.
