A more thorough explanation:

Definition: De clerico capto per statutum mercatorium deliberando is a legal term in Latin that means "for delivering a clerk arrested on a statute merchant." It refers to a writ that orders the release of a clerk who has been imprisoned for breaking a statute merchant.

Example: John, a clerk, was arrested for failing to pay a debt owed to a merchant. The merchant used a statute merchant to secure the debt, which allowed him to have John arrested and imprisoned until the debt was paid. However, John's employer obtained a de clerico capto per statutum mercatorium deliberando writ, which ordered John's release from prison.

This example illustrates how the writ was used to free a clerk who had been imprisoned for breaking a statute merchant. The writ was a legal tool that could be used to protect clerks from being unfairly imprisoned for debts owed to merchants.
