Aresto Momentum is a spell that slows down or stops the movement of an object. Albus Dumbledore used this charm to slow Harry Potter's fall during a Quidditch match in 1993, when he was overcome by Dementors.^[1]

Aresto Momentum is taught at Hogwarts School of Witchcraft and Wizardry, as part of the second-years' Charms curriculum.^[2]

Known practitionersEdit

• Albus Dumbledore^[1]
• Filius Flitwick^[2]
• Hermione Granger^[2][3]

EtymologyEdit

• Likely the combination of two words; the Anglo-French "arester", meaning "to bring to a stop", and the Latin "Momentum", meaning "the force or strength gained whilst moving". Literal translation: "bring its momentum to a stop".

Behind the scenesEdit

• In some of the video games, such as the handheld versions of Harry Potter and the Deathly Hallows: Part 1 and LEGO Harry Potter: Years 1-4, this spell's incantation is spelled Arresto Momento.
• In the second part of the film adaptation of Harry Potter and the Deathly Hallows, Hermione Granger cast this spell when she, Harry, Ron, Griphook and Bogrod fell from the Thief's Downfall to halt them down before they hit the ground below, thus saving their lives.^[4]
• Given its usage in Harry Potter and the Deathly Hallows: Part 2, this spell may be the Cushioning Charm mentioned in the novels. However, this is as of yet unconfirmed.
• This may also be the spell used in the film adaptation of Harry Potter and the Order of the Phoenix when the Dumbledore's Army fell into the Death Chamber in the headquarters of the Ministry of Magic.
