look up the greek translation
Why, pray tell, do you care about the greek origins of effeminate, which the word doesn't even actually originate from, but instead originates from latin?
The closest thing to effeminate in Greek is kinaidos (cinaedus in its Latinized form), and has been speculated to have homosexual connotations. But again, why focus on this? Do you believe that those who originally translated the bible preferred a Greek word and yet used a Latin word so that you could somehow parallel the argument with a word that isn't a natural derivative of effeminate?
The actual roots of effeminate are as follows:
Effeminacy comes from the Latin ex which is "out," and femina which means woman; it means "to be like a woman." The Latin term is mollities, meaning "softness."
So again, you're only making the connection to the Greek definition of a completely different word with different Latin roots because you want too, it actually doesn't have any basis on fact.
