(I) Spells

Impedimenta (Impediment Jinx, Impediment Curse)

Pronunciation: /ɪmˌpɛdᵻˈmɛntə/ im-ped-i-men-təDescription: This powerful spell is capable of tripping, freezing, binding, knocking back and generally impeding the target's progress towards the caster. The extent to which the spell's specific action can be controlled by the caster is not made clear. If this spell does bind, it does eventually wear off as stated inDeathly Hallows.Seen/mentioned: Used in Goblet of Fire when Harry is practising for the third task. Also used by Madam Hooch to briefly stop Harry from fighting with Draco. Also seen toward the end of Order of the Phoenix, when Harry is fighting the Death Eaters. Stronger uses of this spell seem capable of blowing targets away.

Imperio (Imperius Curse)

Pronunciation: /ɪmˈpɪərioʊ/ im-peer-ee-ohDescription: Causes the victim of the curse to obey the spoken/unspoken commands of the caster. The experience of being controlled by this curse is described as a complete, wonderful release from any sense of responsibility or worry over one's actions, at the price of one's free will. Resisting the effect of the curse is possible, however, and several individuals have been able to successfully overcome it, including Harry and both of the Crouches, who learn to resist the curse after being subjected to its effects for an extended period. Harry describes the feeling of being the caster as controlling a marionette through a wand (although Harry's particular experience is suspect due to his lack of commitment to casting Unforgivable Curses). One of the three Unforgivable Curses.Seen/mentioned: First mentioned (not by name) in the first book when Ron told Harry that during the first war Lucius Malfoy claimed that he had been jinxed, thus evading imprisonment. First seen in Goblet of Fire introduced by Barty Crouch Jr. (acting as Moody) and used on a spider. Later seen in the book when Barty Crouch Jr., acting as Professor Moody, used it on all the students to see if they would be able to overcome it. Barty Crouch Sr. had used it on Barty Crouch Jr., who then escaped it and used it on his father before killing him in the fourth book. Used by Harry in Deathly Hallows on a Gringotts goblin and Travers, and by the Death Eaters on Pius Thicknesse.
