Realise software I create is hacked (10)
I believe the answer is:
appreciate
'realise' is the definition.
(I know this)
'software i create is hacked' is the wordplay.
'software' becomes 'app' (software application).
'is hacked' indicates an anagram (I've seen 'hacking' mean this).
'i'+'create'='icreate'
'icreate' with letters rearranged gives 'reciate'.
'app'+'reciate'='APPRECIATE'
(Other definitions for appreciate that I've seen before include "Be grateful for - rise in value" , "prize > increase" , "Enjoy" , "(Of asset) rise in value" , "Welcome" .)
