What is A language ceases to be transmitted?

A language stops being passed down when no one learns it from others anymore.

Imagine you have a favorite song that you love to sing every day. You learn the words from your older sibling, and then you teach them to your little brother or sister. That’s how songs stay alive, by being shared.

Now think about language like that song. When people stop teaching it to others, like when no one learns the words anymore, the language begins to fade away. It's like if your favorite song was only sung by you, and then no one else remembered it, soon, no one would know the song at all.

If a language isn’t passed down from generation to generation, it can disappear completely. That means people who used to speak it might not understand it anymore, just like how your little brother or sister wouldn’t know the words to the song if no one taught them.

It’s like having a special code that only some people know. If no one teaches it to others, eventually, nobody will know what it means!
