ELI5: Explain Like I'm 5

Twilight language

Twilight language is like a secret code that people who belong to a certain group can understand. It’s kind of like how you and your friends have inside jokes or special phrases that only you guys know about.

For example, if you and your friends are big fans of a certain TV show and say “Winter is coming,” you all know it’s a reference to the show and means something special. But someone who doesn’t know the show would just think you're talking about the season of winter.

In the same way, people who belong to certain religious, political or cultural groups use special words or phrases that might not make sense to someone outside of the group. It’s like they have their own secret language!

Twilight language can also be used for secrecy or protection. For instance, if two spies are speaking in public and don't want anyone to understand their messages, they might use a code like "the bird flies at midnight" instead of saying what they really mean. That way, only they know what they are talking about.

So, twilight language is like a secret language or code that certain groups use to communicate with each other or protect their messages from others who might not understand them.
