Summoning Charm

The Summoning Charm (Accio) is a charm that summons an object towards the caster. It is able to summon objects in direct line of sight of the caster, as well as things out of view, by calling the object aloud after the incantation (unless the spell is cast nonverbally). This spell needs thought behind it, and the object must be clear in the mind of the caster before trying to summon it. The opposite of the Summoning Charm is the Banishing Charm.

History
The Summoning Charm is one of the oldest known to wizarding society. This spell's most famous use was, according to Miranda Goshawk, by the Accionites and their leader, Gideon Flatworthy.

In the traditional wizarding tale "The Wizard and the Hopping Pot" from The Tales of Beedle the Bard, the son of the titular pot's original owner Summoned a lost donkey belonging to one of his fellow villagers.

This charm is taught to fourth years at Hogwarts School of Witchcraft and Wizardry in Charms class and is revised again in students fifth in preparation for O.W.L.s. This spell is located in The Standard Book of Spells, Grade 4 by Miranda Goshawk.

Casting and Effects
The Summoning Charm can not be used in buildings. In addition, it will not work on living things, although they may be moved indirectly by summoning things they are wearing or holding. It is risky to summon them in this manner because they travel at close to the speed of light and maybe injured in the process. The only known exception to this rule is Flobberworms, which are generally not considered worth summoning.

The further the desired object is from the caster, the harder it is to summon. Hermione Granger, however, stated that it did not matter how far away the object was — so long as the caster had it clearly in mind, they should be able to summon it with ease. In addition, the object's general location must be known, otherwise, it cannot be summoned.

There exist counter-spells that could be placed on objects to keep them from being summoned. Most wizarding goods sold as of the 20th century and early 21st century came pre-enchanted with an Anti-theft charm to keep them from being summoned by anyone but their rightful owners.

Etymology
The Latin word accio can mean "I call", "I summon", or "action". In the Hungarian translation, the spell is called "Invito", possibly from the word "to invite".
