Dine off Indian meal and fish (6)
I believe the answer is:
animal
'fish' is the definition.
The answer and definition can be both animals as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for animal that I've seen before include "Creature having voluntary movement" , "Living organism characterised by voluntary movement" , "' - - Farm', Orwell" , "One sharing our kingdom" , "something in the zoo?" .)
