Have you ever seen someone use their hands to communicate instead of talking? This is called sign language, and it is used by people who are deaf or hard of hearing. Some countries have recognized sign language as a real language, with its own grammar and vocabulary, just like spoken languages. This is called legal recognition of sign languages.
Legal recognition means that sign language is acknowledged by the government and protected by law. This means that people who use sign language can have access to the same rights and services as those who speak a spoken language. For example, if sign language is recognized as an official language in a country, it means that the government has to provide sign language interpreters in important meetings or hospitals so that deaf people can understand what is being said.
There are some countries where sign language is not yet legally recognized, which means that deaf people may not have access to the same opportunities as those who speak a spoken language. Legal recognition of sign language is important to ensure that everyone has equal access to information, services, and opportunities.
