alma
noun. flower
A word for “flower” derived from primitive ✶galmā in notes on flowers in the same bundle containing Definitive Linguistic Notes (DLN) from 1959 (PE17/153). Initially Tolkien said alma meant both “a blessed thing and a flower”, then said that Q. almë was “a blessed thing” and alba was “flower” (< √GAL-AB), before saying that alma was “flower”. Tolkien implied that alma was a usual or general word for “flower” in Quenya. These same notes also said the word alda < ✶galadā was used mainly of flowering trees. It seems in this instance Tolkien connected the root √GAL (normally just “grow, flourish”) specifically to flowers, giving it the gloss “bloom” along with other glosses like “grow, flourish, be vigorous”.
Neo-Quenya: Elsewhere alda was the general word for a “tree” and √GAL had no special connection to flowers. I think alma as a “flower” word was a transient idea. I would use lótë “flower” instead for purposes of Neo-Quenya, since it is much better established.

lótë noun "flower", mostly applied to larger single flowers (LOT(H), LT1:259, VT42:18). (The shorter form -lot occurs in compounds, e.g. fúmellot, q.v.) In the names Ninquelóte *"White-flower" (= Nimloth), Vingilótë "Foam-flower", the name of Eärendil's ship (SA:loth), also in Lótessë fifth month of the year, "May" (Appendix D). See also olótë, lotsë.
lós (þ?) noun "flower" (PE17:26). If this is to be the cognate of Sindarin loth, as the source suggests, the older Quenya form would be *lóþ.
