Deprive of the least chance? (5)

I believe the answer is:
steal
'deprive' is the definition.
The answer and definition can be both to do with ownership as well as being verbs in their base form.
Maybe you can see a link between them that I don't see?
'the least chance?' is the wordplay.
'least' can be anagrammed to 'STEAL'.
But, I'm not sure how this is indicated.
'of' is the link.
Can you help me to learn more?
(Other definitions for steal that I've seen before include "Creep" , "Rob" , "bargain?" , "bag" , "Filch" .)
