Definition

Adverb: - With full authority of one's office or position: Used to describe a statement or pronouncement made by someone, especially a religious leader like the Pope, in their official capacity and with the expectation of being unquestionably correct or infallible. The term originates from the Latin phrase meaning "from the chair," referring to the seat of authority.

Usage

• It is almost always used after a verb like "speak," "declare," or "pronounce."

Examples
