By combining the Buddhist-specific 尼 (ní) with the common female suffix 姑 (gū), the word 尼姑 was formed as a simple, folk term for a “female Buddhist monastic”. The inclusion of “姑” gives it a more colloquial and less formal feel than its male counterpart, 和尚 (héshang).
In Chinese culture, 尼姑 are women who have chosen to “leave the family” (出家, chūjiā) to live a monastic life dedicated to Buddhism. This involves shaving their heads, wearing simple robes, adhering to a vegetarian diet (吃斋, chīzhāi), and dedicating their lives to studying sutras, meditation, and seeking enlightenment. They typically reside in nunneries, known as 尼姑庵 (nígū'ān). While the English term “nun” is a close equivalent, there are key differences. Unlike a Catholic nun who operates within a hierarchical structure under the Pope, a Buddhist 尼姑 follows the teachings of the Buddha within a specific school or lineage, and there is no single central authority. In Chinese society and literature, they are often portrayed as figures of tranquility and wisdom, detached from the “red dust” of the mortal world (看破红尘, kànpò hóngchén). However, they can also sometimes be depicted as lonely or pitiful figures, having forgone the traditional path of marriage and family, which can contribute to the term's sometimes negative connotation.
This is the most critical section for learners. While 尼姑 is the dictionary definition, using it can be a social minefield.
What to Say Instead (The Respectful Alternatives):
In short: learn the word 尼姑 for comprehension, but use 师父 (shīfu) for communication.
