A monk is a man who devoted part or all of his life to a religion. The word comes from Ancient Greek, and can be translated as "solitary". In Greek, the word can apply to women, but in modern English it is mainly used for men. The word nun is usually used for female monastics. Monks practice asceticism. They either live alone, or together with other monks who share the same ideals. Monks can be found in different religions, most often in Buddhism, Christianity, Hinduism, Jainism and Taoism.
