Burnt fish, like snapper say? (7)
I believe the answer is:
charred
'burnt' is the definition.
(charring is a kind of burning)
'fish like snapper say?' is the wordplay.
'fish' becomes 'charr' (I've seen this before).
'like snapper say?' becomes 'ed' (I am not sure about this - if you are sure you should believe this answer much more).
'charr'+'ed'='CHARRED'
Can you help me to learn more?
(Other definitions for charred that I've seen before include "Cleaned" , "Blackened by fire" , "Partially burnt" , "Slightly burnt" , "Partially burned" .)
