Dear Coffeebean: Nice find. I was able to check it out at Bingley's Perseus site:

I think it a reasonable surmise that the German "über" = "over" comes from this root, ubertas,ubertatis

This is the thing I love most about AWADtalk! Thanks, again, Coffebean

Edit: I just remembered, bad taste to use 'love" for things that cannot return love. Eighth grade English.
