About Sign LanguageLearn More
Sign language is a language that deaf people can use to communicate with each other. English sign language, like English, is considered a complete language.
Sign language is a special regular and advanced language used to convey meaning, instead of audio or written forms in the language, from forms of visual signs (simultaneous combination of shape, direction and movement of hands, arms or body and facial expressions to clearly express the speaker's thoughts). It uses a hint word. Today, an international sign language has been adopted at the world level, of course, elements of the local language are added to it in each region.
