Now Dungrollin:

I'm sitting here with my copy of Chambers English Dictionary, 
worried, because I always interpreted this passage differently...
I'll just quote some bits from the entry for 'stop' (it's quite 
long, so I won't put it all in).

Stop (vt):
to cause to cease, to bring to a standstill; to hinder or prevent 
the passage of ; to prevent (etc etc etc)...
Stopper (n): a person who stops; that which stops; a plug; a plug 
(usu glass) for a bottle; a short rope for making something fast 
(naut). (- vt): to close or secure with a stopper.

I understood 'even stopper death' to mean put death in a bottle with 
a stopper, i.e. 'even bottle death'.  
I'm not going to start a discussion on how JKR uses language 
(although throughout OotP I was getting a little sick of people 
saying things 'breathlessly') but if I had wanted to imply 'even 
prevent death' I'd have used different words, or just said 'even 
stop death'. 

Did anyone else understand it in this way, or am I just being weird?

Cheers,
Dungrollin.
