When given multiple meanings of a word (some scholars think A (eternal) is closer to the actual meaning of the word (aionion) while others think B (everlasting) is closer) isn’t it possible that the true meaning is somewhere in between and there is no exact 1-1 translation into English? Or simply create an English word that has the characteristics, such as we did for the word “benedicere” (literally translated as “speak well of,”) which we know today as “bless.”
As I’ve stated before, English is a great analytic tool and I agree with Viktoria to a point where sometimes more than one word, perhaps a phrase, is necessary to convey the original meaning. I too have done translations, mostly in the dental labs where I worked. Also consider that the Greek itself may be a translation from Hebrew or Aramaic or even Latin (there was a Vetus Latina after all) so as we keep translating we are becoming more and more removed from the original. In many cases it is probably better to leave a word or phrase untranslated or develop some kind of English cognate, as we did with the word “consubstantial.” It may not be understandable to many, but any errors in translation are at least kept to a minimum.
