What is the incantation for the Summoning Charm?

The incantation for the Summoning Charm is Accio.

In the Harry Potter universe, Accio summons a named object to the caster, usually flying through the air into the caster’s hand. Harry learns the spell more effectively during the fourth book, Harry Potter and the Goblet of Fire, when he must summon objects for the first task of the Triwizard Tournament.

Accio is often confused with Alohomora, which unlocks doors and other objects. Lumos creates wand-light, while Expelliarmus disarms an opponent; none of those spells summons anything. The charm also has practical limits: a witch or wizard must identify the desired object clearly, and protective enchantments or distance can interfere with the result.

The word resembles the Latin verb accio, meaning “I summon” or “I call,” fitting Rowling’s broader use of Latin-like spell names. The related opposite is commonly described as an Anti-Summoning Charm, which prevents objects from being called away.
