And so Ribbi becomes Rav.» My inderstand is that Ribbi denotes Semicahh in E"Y and Rav means no such Semichah, owing to "RAV" abba arika only getting a partial semichah. Thus EG Ribbi Yochanan or Ribbi Abahu have the suffix in both Bavli and Yerushalmi, or at least should. ----------------------------------------- Kol Tuv - Best Regards RRW
