Linguistic isolation occurs when a group of people speaks a language that is not understood by surrounding communities. This can happen in remote areas where a unique language develops independently, leading to limited communication with outsiders. Such isolation can affect cultural exchange and access to resources. This phenomenon can also be seen in immigrant communities where individuals maintain their native language, like Spanish or Mandarin, while living in a country where a different language, such as English, is dominant. Over time, this can lead to a decline in language proficiency among younger generations, risking the language's survival.
