The foreign and local fish caught (7)
I believe the answer is:
finnish
'the foreign' is the definition.
I can't judge whether this definition defines the answer.
'local fish caught' is the wordplay.
I cannot really see how this works, but
'local' could be 'inn' (I've seen this before) and 'inn' is present in the answer.
The remaining letters 'fish' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'and' acts as a link.
Can you help me to learn more?
(Other definitions for finnish that I've seen before include "Eg, native to Helsinki" , "Nationality of citizens of Helsinki" , "race" , "foreign language" , "European language" .)
