"Harry aimed his wand at Peeves and said, "Langlock!" Peeves clutched at his throat, gulped, then swooped from the room making obscene gestures but unable to speak, owing to the fact that his tongue had just glued itself to the roof of his mouth."
—Harry Potter's use on Peeves the Poltergeist in the Hogwarts hospital wing[src]

Langlock[1] was the incantation of a jinx that caused one's tongue to affix to the roof of their mouth. It was known to work on humans[2] as well as on spirits (including a poltergeist, like Peeves).[1] It was most likely invented for the sake of preventing someone from speaking aloud or even to prevent a spell from being cast.

History

It was invented by Severus Snape and recorded in his copy of Advanced Potion-Making while he was a student at Hogwarts School of Witchcraft and Wizardry in the 1970s.[3]

It is unknown when Severus Snape invented this and many of his other spells, as according to Sirius Black "he knew more curses when he arrived at school than half the kids in seventh year."[5]

During the 1989–1990 school year, Bill Weasley taught this jinx to a group of sixth year students in one of his Defence Against the Dark Arts tutoring sessions.[6] Ben Copper would later use this jinx to incapacitate fellow Gryffindor Charlie Weasley when the latter, beside himself with distress, angrily reproached Jacob's sibling.[7]

Harry Potter found out about the spell in the 1996-1997 school year when he gained possession of Snape's copy of Advanced Potion-Making. He used Langlock on Argus Filch twice during the school year "to general applause",[2] and again on Peeves.[1]
