How do you address a monk?

Answer 1

For monks within Christianity:

In the Roman Catholic (Benedictine/Cistercian) tradition:

for a monk who is not a priest use the title "Brother"

also, a monk, once he has made vows is called "Dom" (or "Don") in some places (particularly in the Cistercians and some Benedictine congregations).

If a monk is also a priest he is called "Father"

The abbot is referred to as "Father Abbot" or "Reverend Father"

in Eastern Christianity (Orthodox Churches and Greek Catholic Churches) there are different traditions for addressing monks, and I am not competent to answer for that tradition since I come from the Roman Catholic tradition.

Answer 2

When addressing a monk, it is important to show respect by using the appropriate title. In many traditions, monks are addressed as "Venerable" followed by their first or last name. For example, you might address a monk as "Venerable John" or "Venerable Smith." It is also common to bow slightly as a sign of respect when addressing a monk.
