So imagine if your mommy and daddy knew two different languages. Maybe your daddy speaks Spanish and your mommy speaks English. Sometimes, they might mix those two languages together when they talk to each other. That's kind of what happened with Judeo-Persian.
Judeo-Persian is a language that was spoken by Jewish people who lived in parts of what is now Iran, Afghanistan, and Tajikistan a long time ago. These Jewish people spoke a language called Persian that was used by a lot of people in that area, but they also knew a special kind of Jewish language called Hebrew.
When these Jewish people talked to each other or wrote letters, they would mix Persian and Hebrew together. So some of the words they used were in Persian, but some of them were in Hebrew. Over time, this mix of languages became its own thing - Judeo-Persian.
Judeo-Persian is a really cool language because it combines words, grammar rules, and sounds from different languages. It's like the mommy and daddy languages of the Jewish people in those areas had a baby language! Today, it is not spoken as much, but it remains an interesting piece of history and culture among Jewish communities.
