Question: What is a verb for *illusion*? I want to use it in a sentence like the following:

> 
> The optical effect [illudes] my perception of its real shape.
> 
> 
> 

But **illude** does not exist. But I cannot find *illude* in my Dictionary (OS X Dictionary.app). I want to find a verb that is somewhere between *deceive* and *confuse*.

Answer: 
Perhaps too extreme, but *perverts* might work. Or better maybe, *subverts*.
You could use *illusory*, which is an adverb.
