Rebellious chief of staff to reword loan receipts (9)
I believe the answer is:
seditious
'rebellious' is the definition.
(thesaurus)
'chief of staff to reword loan receipts' is the wordplay.
'chief of' indicates taking the first letters.
'to reword' becomes 'edit' (I've seen this in another clue).
'loan receipts' becomes 'ious' (I can't justify this - if you can you should believe this answer much more).
The first letter of 'staff' is 's'.
's'+'edit'+'ious'='SEDITIOUS'
Can you help me to learn more?
(Other definitions for seditious that I've seen before include "Revolutionary" , "Inciting to revolt" , "Rabble-rousing" , "inciting rebellion" , "undermining the state" .)
