The Impediment Jinx, also known as the Impediment Curse, is a spell which impedes forward motion, either slowing or stopping an object or individual, effectively immobilising them for a short period of time. When cast with power, however, it may knock the target off their feet. It has sometimes knocked the target over, but not prevented movement. Whether these variations are accidental in the casting of the spell, or the choice of the caster, is unclear. It can also sometimes just levitate people in an act that is like that of the spell Levicorpus.^[1]

Etymology

Impedimenta is devised from the Latin word Impedimentum, meaning "a hindrance".

Behind the scenes

• It is debatable whether the spell is a jinx, or a hex. In Harry Potter and the Goblet of Fire, Order of the Phoenix and Half-Blood Prince, it is called a jinx. In Fantastic Beasts and Where to Find Them, it is referred to as a hex.
• Impedimenta is a usable spell in Harry Potter and the Deathly Hallows: Part 1 (video game). Which, in the game, if used rapidly, it will defeat an opponent. However in Harry Potter and the Deathly Hallows: Part 2 (video game) it is a long range shot which will split up and strike multiple targets, making them disappear at once. Its depiction is almost like homing missiles.
