The Sectumsempra Spell (Sectumsempra) is a curse that inflicts deep, potentially fatal wounds in the victim[1]. It was invented by Professor Severus Snape under his alias of "The Half-Blood Prince"[2], in his first year at Hogwarts School of Witchcraft and Wizardry[3].

  3. Sirius Black states that Snape "knew more curses when he arrived at school than half the kids in seventh year", meaning that he knew curses few others had even heard of. By his fifth year, Snape had used the spells often enough that James Potter I, who would only ever have heard of their use from Snape, could repeat them non-verbally and at a second's notice.
