Finite

From UnknowableWiki

Finite is a spell used to cancel out the effects of a charm at work.

Remus Lupin uses the spell in order to stop Neville Longbottom's legs from moving uncontrolably due to the Tarantallegra spell previously cast on him by Antonin Dolohov, during the Battle of the Department of Mysteries (OP36).

Harry Potter uses Finite to cancel out the effect of the Descendo charm cast by Vincent Crabbe on a fifty foot pile of furniture in the Room of Hidden Things, preventing the objects of falling on top of Ron Weasley (DH31).

Finite is likely to be the same spell as Finite Incantatem, due to the similarity of the names and the effects, but this possibility was never confirmed.
