Explanation

You may know the custodian at your school — the person who's in charge of taking care of the building, in keeping it clean, making sure the heat works, and the roof doesn't leak. The word custodian comes from Latin custos, meaning "guardian," and anyone who looks after something can be a custodian. You might be the custodian of your club's records — you take care of the files and keep them up to date. Or you could be the custodian of the crown jewels — you hold the keys to the treasury and it's your job to make sure the jewels don't get lost or stolen.
