Judeo-Spanish is a type of language that is spoken by Jewish people who came from Spain a long time ago. It has a mix of Spanish words and words from other languages that were spoken by the Jewish people over time. It is also sometimes called Ladino. People who speak Judeo-Spanish might use it to talk to other people who also speak it, or they might use it to keep the language and culture of their ancestors alive. It's like having a secret code that only some people can understand!
