The term "Girolamo Savonarola" refers to a specific historical figure rather than a common English word. Here’s an easy-to-understand explanation:
Girolamo Savonarola was an Italian priest and a reformer who lived from 1452 to 1498. He was part of the Dominican order, which is a group of religious monks. Savonarola is known for his strong preaching against sin and corruption, especially during a time when the church and society had many problems. He gained a large following in Florence, Italy, where he became very influential. He even helped to drive out the powerful Medici family from the city. However, his outspoken criticism of the Pope and the Catholic Church eventually led to him being excommunicated (which means he was officially kicked out of the church) and executed (killed) for his beliefs.
