ius primae usufructus is a Latin phrase used by Sister Justinian to explain why after fifty years of teaching that Sister Coroda has certain rights with college equipment over others (Saint Fidgeta and Other Parodies, 74).


The phrase is Latin for “right of first use and enjoyment”, possibly inspired by the expression "jus primae noctis" (“right of the first night”), the right of a nobleman to sleep with any of his (presumably female) vassals on her wedding night[1].
