the DE had been able to cast it verbally. Has there been any other 
reference to this? I'm assuming then that you certainly couldn't do 
a successful AK or crucio spell nonverbally.

Allie:

I'm inclined to agree with you, although I think the power of the 
wizard would influence the strength of the spell also.  Then there 
are spells like "levicorpus" which are nonverbal by design.  I would 
guess that certain spells have the same result whether spoken or 
nonverbal, for example, a vanishing spell would have the same result 
whether verbal or not - the object is still gone.  But something 
like requires a lot of power, like sectumsempra, maybe, wouldn't be 
as severe if nonverbal.
