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”.
