Pronounced: (just like it sounds), noun
Notes: I didn’t know this phrase, but it is common
The word eudemonic means “pertaining to or conducive to happiness; related to theories of happiness”
Our word came into English in the mid-1800s
Background / Comments
The word comes from the Greek word eudaimonikós, which comes from eudaimōn (blessed with a good genius, fortunate, happy). My original guess of eu- combined with demon and -ic was correct, but apparently, daimōn – the Greek base for demon – could also mean “destiny” or “fortune”.
