SPELLS DICTIONARY-W
Used by Remus Lupin in PoA to expel a wad of chewing gum from the key hole Peeves put in and launch it up Peeves's nose. Latin "vadi vasi" roughly means rush (away) stuff. (The Latin letter V is pronounced like the English letter W.) Specific function not clear. Possibly launches a small "wad" of any sort in the direction desired by the caster.
This spell levitates objects. First seen in Professor Flitwick's class, when the first years practice the spell with feathers. In the movie, it is used by saying "Wingardium Leviosa!" while making a "swish and flick" movement with the wand. "Wingardium" is a combination of the English word "wing" and the Latin word "arduus" (meaning "steep") and "leviosa", which contains the Latin word "levare" (meaning "ease, lift, pick up").
