It's a fish from somewhere in India, love (6,4)
I believe the answer is:
bombay duck
'it's a fish' is the definition.
(I've seen this before)
'in india love' is the wordplay.
'in india' becomes 'bombay' ('Bombay' is part of 'india').
'love' becomes 'duck' (I've seen this before).
'bombay'+'duck'='BOMBAY DUCK'
'from somewhere' is the link.
This may not be correct. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for bombay duck that I've seen before include "one being caught in the deep?" , "Dried curried fish" , "Fish (as curry savoury)" , "Small Indian fish" , "Dried fish dish" .)
