1.
Buddhist priest; monk; abbot; head priest of a temple
A senior Buddhist priest, particularly the head or chief priest of a temple. Also used informally to refer to any Buddhist priest.
The reading varies by Buddhist sect: おしょう is standard (especially Zen), but かしょう (Tendai/Shingon) and わじょう (other sects) are also used. In everyday speech, 和尚さん (with the polite さん suffix) is the most common form, used much like calling someone "Father" in Christianity.
