"Tzitzit" (Hebrew: צִיציִת) (Ashkenazi pronunciation: "tzitzis") are special knotted "fringes" or "tassels" found on the four corners of the "tallit" (Hebrew: טַלִּית) (Ashkenazi pronunciation: "tallis"), or prayer shawl. The "tallit" is worn by Jewish men and some Jewish women during the prayer service. Customs vary regarding when a Jew begins wearing a tallit. In the Sephardi community, boys wear a tallit from bar mitzvah age. In some Ashkenazi communities, it is customary to wear one only after marriage. A "tallit katan" (small tallit) is a fringed garment worn under the clothing throughout the day. In some Orthodox circles, the fringes are allowed to hang freely outside the clothing.
