A more thorough explanation:

Term: quietare
Definition: In the past, when people made legal agreements, they sometimes used the word "quietare" to mean that someone was being let go without any punishment or blame. For example, if someone owed money to another person, they might make an agreement that said the debtor would pay the money back, and then the creditor would "quietare" them, meaning they wouldn't be punished or blamed for owing the money. This word was used in legal documents called conveyances.
Examples:

• After John paid back the money he owed to Sarah, she quietared him so he wouldn't be punished for not paying on time.
• The judge quietared the defendant after finding him not guilty of the crime.

These examples show how "quietare" was used in legal agreements to mean that someone was being let go without any punishment or blame.
