Two drawings show two different signs in São Tomé and Príncipe Sign Language with brief explanation in text.

If no one teaches them, some Deaf people grow up without language. But if Deaf people find each other and form a community, they will eventually create a sign language of their own. Therefore, one of the newest languages in the world is the São Tomé and Príncipe Sign Language. São Tomé and Príncipe is an African island nation near the equator. Meanwhile, the country São Tomé and Príncipe has an unusually high ratio of Deaf people. Additionally, many of them had no language or education. In response, a project brought together Deaf people in the country. During their first two years in forming a community, Deaf people in São Tomé and Príncipe evolved a new language. Researchers analyzed the language and how it has evolved.
