Incarcerous (Incarcerous Spell)

Type: Conjuration

Pronunciation: in-KAR-ser-us

Description: Ties up the target with ropes conjured from thin air.

Seen/Mentioned: First heard in 1996, when Dolores Umbridge tries to hold off Centaurs. Also used by Harry on the Inferi in Voldemort's Crystal Cave in 1997 and also attempted to use it on Severus Snape in the same year.
Etymology: Probably English incarcerate, "to imprison". Possibly linked to the Latin in carcerem, "in(to) prison".

Notes: A non-verbal version of this spell may have been used to tie up Remus Lupin by Severus Snape during the encounter in the Shrieking Shack, and then later Peter Pettigrew in 1994. It may also have been used by Quirrell in 1992, although he is said to have merely "snapped his fingers". Also, it may have been the spell Antonin Dolohov used non-verbally to bind Ron Weasley with "shining black ropes" in a skirmish on Tottenham Court Road.

Notes (2): It can be bought at Wiseacre's Wizarding Equipment in Diagon Alley in LEGO Harry Potter: Years 1-4.
