Prohibition is international, an order with little right in it (9)
I believe the answer is:
interdict
'prohibition' is the definition.
(thesaurus)
'international an order with little right in it' is the wordplay.
'international' becomes 'int'.
'an order with' becomes 'edict' (I can't justify this - if you can you should give a lot more credence to this answer).
'little' suggests taking the first letters.
'in it' indicates putting letters inside.
The initial letter of 'right' is 'r'.
'edict' placed around 'r' is 'erdict'.
'int'+'erdict'='INTERDICT'
'is' acts as a link.
Can you help me to learn more?
(Other definitions for interdict that I've seen before include "Ban" , "Decree" , "Credit tin (anag) - ecclesiastical sanction" , "Prohibit, forbid" , "Prohibit - tin credit (anag)" .)
