Record hybrid of coca and nut (7)
I believe the answer is:
account
'record' is the definition.
(account is a kind of record)
'hybrid of coca and nut' is the wordplay.
'hybrid of' is an anagram indicator (I've seen 'hybrid' mean this (I've seen this in other clues)).
'and' means one lot of letters go next to another.
'coca'+'nut'='cocanut'
'cocanut' anagrammed gives 'ACCOUNT'.
(Other definitions for account that I've seen before include "Description; importance" , "Bill - narrative" , "Charge" , "History" , "Story; bank service" .)
