I want to know the answer to the following question:
What was the original definition of a cardinal priest?
All the background I'm provided with is that "Originally, however, this referred to certain key priests of important churches of the Diocese of Rome, who were recognized as the cardinal priests, the important priests chosen by the pope to advise him in his duties as Bishop of Rome (the Latin cardo means "hinge").". Is that enough to answer the question?
Answer: yes
