I want to know the answer to the following question:
Which church still holds on to the original meaning of "cardinal" from the above Latin word?
All the background I'm provided with is that "The term cardinal at one time applied to any priest permanently assigned or incardinated to a church, or specifically to the senior priest of an important church, based on the Latin cardo (hinge), meaning "principal" or "chief".". Is that enough to answer the question?
Answer: no
