In SE Milan, somehow seedy, in a sense (7)
I believe the answer is:
seminal
'in' is the definition.
Both the definition and answer are adjectives. Maybe there's a link between them I don't understand?
'se milan somehow seedy in a sense' is the wordplay.
'se milan' anagrams to 'SEMINAL'.
Though, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for seminal that I've seen before include "Generating new developments for menials" , "Original and influential" , "Having strong later influence" , "Majorly influential" , "Strongly influential" .)
