- "Chasers were also becoming increasingly irritated by the necessity of diving continually towards the ground to retrieve the Quaffle and so, shortly after the Quaffle's change of colour, the witch Daisy Pennifold had the idea of bewitching the Quaffle so that if dropped, it would fall slowly earthwards as though sinking through water, meaning that Chasers could grab it in mid-air."
- —Description of the spell's invention[src]
Arresto Momentum is the incantation of a charm that can be used by a witch or wizard to slow the velocity of an object. It is taught in second year Charms class at Hogwarts School of Witchcraft and Wizardry.
|Severus Snape||18 September, 1995||Snape used this spell to prevent Brody Hudson from falling to death after he fell of his broomstick during his practise for Quidditch tryouts.|
- 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".
