What is the suffix of priests?

There isn't a single universal suffix for priests. The suffix used depends on the religion or denomination.

Here are some examples:

* Catholic: "Father" (e.g., Father John)

* Orthodox: "Father" (e.g., Father George)

* Anglican: "Father" or "Reverend" (e.g., Father David, Reverend Peter)

* Presbyterian: "Reverend" or "Pastor" (e.g., Reverend Mary, Pastor Michael)

* Jewish: "Rabbi" (e.g., Rabbi Cohen)

* Islam: "Imam" (e.g., Imam Ali)

* Buddhism: "Bhikkhu" (for monks), "Bhikkhuni" (for nuns)

* Hinduism: "Pandit" (for scholars), "Pujari" (for temple priests)

So, the specific suffix will vary depending on the religious tradition.
