What is the definition or usual translation for the word "Adderabba"? I sometimes find it as an interjection in Jewish blogs and forums, so it is not easy to figure out the meaning from the context. On Mi Yodeya, I found it four times (not counting this question), possibly all written by DoubleAA.
Wikimilon (Hebrew Wiktionary) suggests: On the contrary.
Actually it has two meanings:1. "On the contrary", and 2. "More so".
The literal definition is more so. you can see a discussion (hebrew) in the hebrew language forum
