A word in notes from the 1960s for a “(golden) blossom” with variants löar and lávar, both based on the √LAWAR having to with the colour “gold” (PE17/159). The element ᴹQ. lavar also appeared as an element in the name for a Númenorean tree ᴹQ. lavaralda in stories from the 1930s which Tolkien described as having “long green leaves [that] were golden on the undersides” and whose “flowers were pale with a yellow flush” (LR/57-68). For purposes of Neo-Quenya, I would use lávar for “(golden) blossom”, since that form is more distinctive.
