Silencing Charm

"The raven continued to open and close its sharp beak, but no sound came out."

- Description

The Silencing Charm (Silencio) is a charm that renders the victim temporarily mute, working on both beasts and beings. It is immensely difficult to perform, more so on ravens than frogs.

Professor Filius Flitwick had his fifth year Charms students practice this spell at Hogwarts School of Witchcraft and Wizardry, and assigned it as homework to those who could not perform it competently in class.
