Qenya
herenya
adjective. wealthy, rich, blessed, fortunate
Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!
A word in The Etymologies of the 1930s glossed “fortunate, wealthy, blessed, rich”, an adjectival form of ᴹQ. heren “fortune” under the root ᴹ√KHER “rule, govern, possess” (Ety/KHER). Tolkien indicated the literal meaning of the noun was “governance”, and its actual sense is “what is in store for one and what one has in store”. As such I think its adjective form has a meaning closer to “wealthy, rich = imbued with fortune (earned or expected)” rather than “fortunate = lucky”.
