Liberare comes from the Latin verb liberare which means "to free".
Behind the scenes
- This spell is mentioned only in the script of Harry Potter and the Prisoner of Azkaban.
- The etymology of the spell is similar to the spells Relashio and Emancipare , which are also etymologically derived from Latin for "set free". It is however hypothetical in the case of Emancipare, not only due to its conjectural nature, but that it is also similar to The Disarming Charm. It forces the target to drop what the target is holding. Relashio releases a targets grip, thus may disarm them.
