Rabi or Rabbi: Which Spelling Is Correct?

Have you ever written rabi or rabbi and stopped to wonder which spelling is correct? These two words look almost the same, but they can have different meanings. 

This is why people often search for “rabi or rabbi” when writing about Jewish religious leaders, names, or other words that sound similar.

The correct spelling depends on what you mean. Rabbi is the standard English spelling for a Jewish religious teacher or leader. 

For example, you might write, “The rabbi spoke to the congregation.” Rabi, with one “b,” is not normally the standard spelling for this meaning in English. 

However, “Rabi” can appear as a name, transliteration, or part of a word in other languages and contexts.

Knowing the difference helps you avoid spelling mistakes in emails, articles, school work, news writing, and formal documents. 

In this guide, we will explain the origin of both spellings, compare British and American English usage, show common mistakes, and give clear examples.

The Origin of Rabi or Rabbi

The word rabbi comes from Hebrew. It is related to the Hebrew word rav, meaning “great,” “master,” or “teacher.” 

The form rabbi developed as a respectful title meaning roughly “my master” or “my teacher.”
