The name for this spell is mentioned in (OP19).

Summoning Charm

"Accio" (see pronunciation notes)

"accio" L. send for, summon

Source: The Book of Spells, Chapter 4

Accio Causes an object to fly to the caster, even over quite some distance; the target object is said to have been Summoned. It would seem that the caster must know at least the general location of the object Summoned.

NOTE: The pronunciation of this spell has been debated by fans. The "official" pronunciation from Scholastic is "A-see-oh." This is the pronunciation used in the audio version of the books. The word is Latin, however, and in Latin the letter C is always pronounced 'hard,' the same as the letter K. Some languages which are descended from Latin, such as Italian, pronounce 'cc' as 'ch,' but this is almost certainly not correct. UPDATE: In the Book of Spells, Accio is pronounced "ACK-see-oh"

Supersensory Charm

A category of Transfiguration spells that swap one thing for another.
