Unlocking Charm

"Stand back! ... Alohomora!"
-- Hermione Granger, rescuing Sirius Black from Professor Flitwick's Office (PA21)

Unlocking Charm

The Unlocking Charm is a charm that causes a locked door to open.

History and Notes

  • The Unlocking Charm was invented in Africa (the origin of the incantation word is from the country of Madagascar (SDNY)). It was brought to Britain in the early 1600s by a wizard thief named Eldon Elsrickle (BoS).
  • Earlier unlocking spells were much more violent, resulting in damage to the lock ("Portaberto") or to the entire door ("Open Sesame") (BoS)

Etymology

The term ‘Alohomora’ comes from sikidy, a form of divination from the Malagasy people of Madagascar. It is the name of a magical symbol which means ‘favourable to thieves’ (trans.). (thanks to Rattlesnakeroot and her LJ friends for discovering this.)
