contaminate

I'm a little stuck... Click here to teach me more about this clue!

'corrupt' is the definition.
(thesaurus)

'conservative with old african dictator in art gallery' is the wordplay.
'conservative with old african' becomes 'con' (I can't explain this - if you can you should believe this answer much more).
'dictator' becomes 'amin' (Idi Amin, Ugandan dictator).
'in' is an insertion indicator.
'art gallery' becomes 'tate' (Tate Modern, Tate Britain etc).
'amin' inserted inside 'tate' is 'taminate'.
'con'+'taminate'='CONTAMINATE'

Can you help me to learn more?
