Muffliato is a charm that fills a surrounding area with an unidentifiable buzzing, so to provide a private environment for a conversation in a public place. The caster may have lengthy, intimate conversations without being overheard. It was invented by Severus Snape while he was a student at Hogwarts School of Witchcraft and Wizardry.
Hermione Granger originally disapproved of using the spell, but came to use it herself when it was needed; for example, to protect the campsite she shared with Harry and Ron Weasley when they hunted for Lord Voldemort's Horcruxes between 1997-1998.
Etymology
- The English word muffle means "to make a sound less distinct by covering its source".
