Fish I am brought in to identify (6)
I believe the answer is:
plaice
'fish i' is the definition.
'plaice' can be an answer for 'fish' (I've seen this before). I'm not certain of the 'i' bit.
'am brought in to identify' is the wordplay.
'am' becomes 'i' (I can't justify this - if you can you should give a lot more credence to this answer).
'brought in to' is an insertion indicator.
'identify' becomes 'place' (synonyms).
'i' put within 'place' is 'PLAICE'.
Can you help me to learn more?
(Other definitions for plaice that I've seen before include "N. Atlantic flatfish" , "Large flatfish" , "Large flat fish" , "Type of fish" , "Location of the fish" .)
