Report misspelling of coca nut (7)
I believe the answer is:
account
'report misspelling' is the definition.
'account' can be an answer for 'report' (I've seen this in another clue). I'm not sure about the 'misspelling' bit.
'of coca nut' is the wordplay.
'of' is an anagram indicator (the answer comes from or 'of' the letters).
'coca'+'nut'='cocanut'
'cocanut' with letters rearranged gives 'ACCOUNT'.
Can you help me to learn more?
(Other definitions for account that I've seen before include "Bank record" , "credit arrangement" , "Report of an event" , "judge" , "Bill - relation" .)
