Anapneo

From Hpwiki

Logic would suggest that Anapneo was derived from quite well-known Greek roots.

A- or an- means not or un. (Hence a-tom, not cuttable; an-algesia, no pain; an-archy, no ruler.)

Pneu- is the root for breath, as in pneumatic or pneumonia. Thus Anapneo would either stop breathing, or create a sensation of having shortness of breath.

Used in the books:

• Professor Slughorn uses it in Harry Potter and the Half-Blood Prince to cleary Marcus Belby's airway when he chokes
