Extraordinary NonVerbal Spell

A nonverbal spell was a spell which was performed without the casting wizard or witch speaking the incantation aloud. Hogwarts School of Witchcraft and Wizardry began teaching nonverbal magic to students in their sixth year in Defence Against the Dark Arts, Charms, and Transfiguration; the students were expected to use spells nonverbally from then on.
==Performance==
Performing spells non-verbally was very difficult and required a good deal of practice, as it required concentration and mental discipline alone. Harry Potter noted that several students in his class looked "like they had received an overdose in U-No-Poo", (a product of Weasley's Wizard Wheezes that caused constipation), while attempting nonverbal spells.
Different wand-woods might also affect the performance of casting non-verbal magic. Many wands made from Dogwood were rather noisy, and refused to perform non-verbal magic, whereas wands of Pine were some of the most sensitive to non-verbal magic. Willow wands possessed a well-founded reputation for enabling advanced, non-verbal magic, but of all woods, Alder was known as being the best suited for non-verbal magic.
===Effectiveness===
Some spells, such as Levicorpus, were easier to perform nonverbally than others. Most spells, however, seemed to be less effective than normal when the incantation was not said. For example, according to Hogwarts nurse Poppy Pomfrey, the unnamed curse that critically injured Hermione Granger during the Battle of the Department of Mysteries might have been fatal had Antonin Dolohov not been silenced when he used it.

==Behind the scenes==
*In many of the Harry Potter films, especially in the later ones, combat and duels are portrayed as being conducted almost entirely nonverbally, such as the Duel in the Ministry Atrium and Harry's final duel with Voldemort during the Battle of Hogwarts. This is probably done to keep the duels fast-paced and dramatic. It may also be that gestures or wand movements translate into the spell that the user desires to cast, making it not always necessary to speak it.
*In , Quirrell used a non-verbal wandless spell to start up some fire in order to stop Harry Potter from running.
*Hermione Granger may have used Wingardium Leviosa or Descendo in to levitate the prophecies to smash one of the Death Eaters chasing them.
*It is notable that Rubeus Hagrid was able to perform non-verbal magic despite him having been expelled from Hogwarts well before his sixth year and despite having had his wand snapped. This means that if a wizard or witch is sufficiently talented, they can perform non-verbal magic effectively even if they had not been trained in its use.
*In a chat with fans on the-leaky-cauldron.org J. K. Rowling answered a fan's question why Albus Dumbledore was sometimes able to see Harry under the Cloak of Invisibility that he used the Revelio Charm with non-verbal magic.J.K. Rowling Web Chat Transcript on the-leaky-cauldron.org
*In the film , Gellert Grindelwald casts Protego Diabolica nonverbally. This is not canon, as he speaks the incantation aloud in the script itself.
