untouchable

An untouchable person or thing is someone or something that can't be changed, affected, or controlled by anyone else.

The word "untouchable" is often used to describe people who are above the law, like a politician who has connections and power. You might hear about an untouchable celebrity who's been accused of something but still keeps their fame because they're so well-known and influential. It can also mean someone or something that's extremely powerful or respected, making it hard for others to touch or influence them in any way. For example, a famous athlete might be considered untouchable on the field due to their incredible skills and reputation.
