Ῥαββεί. (2 verses](Hebrew word) "Rabbi" is not from any Greek word, though listed in Strong's as rhabbi, but the Hebrew rab, which means, as an adjective,  "much," "many," "great," "strong," and "greater than." As a masculine noun, it means "captain" or "chief."   - "Rabbi" is from a Hebrew word, not a Greek word, and adjective that means "much," "many," "great," "strong," and "greater than." As a masculine noun, it means "captain" or "chief."  Jesus only used it in  Matthew 23:7 and Matthew 23:8, telling others not to use it. All other use of this word are by others addressing Jesus, which seems like an inside Joke.
