The Vietnamese word "cha cố" refers to a clergyman or clergy, particularly in the context of the Catholic Church. It is a term used to describe a priest who is often responsible for a particular church or religious community.
In a more advanced context, "cha cố" can also refer to a priest who has a significant role in the community, often seen as a leader or guide.
While "cha cố" primarily refers to a clergyman, it can also be used in more general discussions about religious leadership or authority figures within various faiths, though it's most closely associated with Catholicism.
