Original: Thus, the title gained an irregular plural form: Ö 'Ö Ö 1\/4 Ö Rabbanim ("rabbis"), and not Ö' Ö Ö 1\/4 Rabbai ("my Masters"). There is a mitzvah to stand up for a Rabbi or Torah Scholar when they enter your presence.
Simplified: Rabbi (in the Hebrew classic Ö 'Ö Ö 1\/4 ribbi; in the Hebrew modern Ö' Ö Ö 1\/4 rabbi) in Judaism signifies "professor, master" or literally "grand".
