Malfoy's spell

[alora]

I know I asked this question when CoS was released, but I think I 
will ask it again.  Does anyone understand what spell it is that 
Malfoy casts at Harry when they duel?  The first one - it sounds 
something like "invertea"  or "invertae"  (or inverted?) and then 
another word.  I've seen the movie 4 times and I still can't hear it 
correctly because of the sound effects in the movie.  

And I get to see the movie again next Thursday, which isn't a big 
deal.  BUT - I get to see it DIGITALLY!  I am soooo excited.  My 
husband got invited to see some sort of presentation on digital 
movies/film and how it is going to be more prominent in the future.  
Frankly, I don't care about that, but I do care about seeing it in 
digital.  Supposedly, the clarity is much better.  I'm hoping to see 
more color, costume details, etc.  It should be fun, anyway.
