Effect	Sealed mouth shut

Oscausi was the incantation of a Dark charm that could be used to seal someone's mouth shut. The victim's mouth would appear as if it was never there, with skin covering the area. The victim would also be muted as a consequence.

History

This spell was used by Leta Lestrange on a girl from Gryffindor when they were both in their third year at Hogwarts School of Witchcraft and Wizardry. The Gryffindor girl was speaking spitefully of Lestrange behind her back until Lestrange emerged from hiding nearby, and muted the Gryffindor girl with this spell. Minerva McGonagall reversed the spell, but when the girl continued to complain about Leta, the irritated McGonagall recast the spell.

Etymology

Oscausi is possibly derived as a portmanteau of os, Latin for "mouth", and clausi (a conjugated form of claudo), Latin for "I shut". It may also be a pun or wordplay on scusi, the Italian interjection for "excuse me".
