A rite or ritual is an established, ceremonial, usually religious, act. Rites in this sense fall into three major categories:

• rites of passage, generally changing an individual's social status, such as marriage, adoption, baptism, coming of age, graduation, or inauguration;
• communal rites, whether of worship, where a community comes together to worship, such as Jewish synagogue or Mass, or of another character, such as fertility rites and certain non-religious festivals;
• rites of personal devotion, where an individual worships, including prayer and pilgrimages such as the Muslim Hajj, pledges of allegiance, or promises to wed someone.
