uncultured

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

'ignorant' is the definition.
(thesaurus)

'a foreign way of life taken on by duke' is the wordplay.
'a foreign' becomes 'un' ('a' translated into French).
'way of life' becomes 'culture' (I can't explain this - if you can you should believe this answer much more).
'taken on by' means one lot of letters go next to another.
'duke' becomes 'd'.
'un'+'culture'+'d'='UNCULTURED'

'of' acts as a link.

Can you help me to learn more?
