Not all of the world’s languages are written. Language is actually oral above all else: we speak it and hear it. Writing a language means that we are giving it a visual aspect, that is to say a graphic one. We therefore use graphic symbols to visually represent and transcribe the oral language. Like the oral language, the written language allows communication to happen.
The spoken word is ephemeral. Writing permits us to register it visually and therefore conserve it longer.
