I've the version to steal (6)
I believe the answer is:
thieve
'to steal' is the definition.
(I know that thieve is a more specific form of the action theft)
'i've the version' is the wordplay.
'version' indicates an anagram.
'ive'+'the'='ivethe'
'ivethe' anagrammed gives 'THIEVE'.
(Other definitions for thieve that I've seen before include "appropriate" , "Knock off" , "Pilfer" , "Misappropriate" , "Pinch" .)
