A more thorough explanation:

Definition: Calling to the bar refers to the admission of a person to practice law.

This phrase comes from the Latin term "ad barram evocatus," which means "called to the bar." When someone is called to the bar, they are officially recognized as a lawyer and can practice law.

For example, after completing law school and passing the bar exam, a person may be called to the bar in a formal ceremony. This marks the beginning of their career as a practicing lawyer.

Another example is when a lawyer from one country wants to practice law in another country. They may need to be called to the bar in that country before they can practice law there.

Overall, calling to the bar is an important step in becoming a lawyer and being able to practice law.
