A temple (from the Latin templum) is a place of worship, a building used for spiritual rituals and activities such as prayer and sacrifice. By convention, the specially built places of worship for some religions are commonly called "temples" in English, while those of other religions are not, even though they fulfill very similar functions.
The religions for which the terms are used include the great majority of ancient religions that are now extinct, such as the Ancient Egyptian religion and the Ancient Greek religion. Among religions still active: Hinduism (whose temples are called mandir or kovil), Buddhism (whose temples are called vihara), Sikhism (whose temples are called gurudwara), Jainism (whose temples are sometimes called derasar), Zoroastrianism (whose temples are sometimes called agiary), the Baháʼí Faith (which are often simply referred to as Baháʼí House of Worship), Taoism (which are sometimes called daoguan), Shinto (which are often called jinja), Confucianism (which are sometimes called the Temple of Confucius).
