A Siddur is a Jewish prayer book that contains a set order of prayers and blessings for daily, Shabbat, and holiday services. It serves as a guide for worshippers, helping them connect with their faith through structured prayers and rituals. The word "Siddur" comes from the Hebrew root meaning "order," reflecting the organized nature of the prayers. The Siddur includes various sections, such as the Shacharit (morning prayers), Mincha (afternoon prayers), and Maariv (evening prayers). It may also contain additional readings, such as the Torah portions and special prayers for occasions like weddings or funerals. Different Jewish communities may have their own versions of the Siddur, reflecting diverse traditions.
