Ban dire criminal entering international court (9)
I believe the answer is:
interdict
'ban' is the definition.
(I know that interdict is a type of ban)
'dire criminal entering international court' is the wordplay.
'criminal' indicates anagramming the letters.
'entering' indicates putting letters inside.
'international' becomes 'int' (abbreviation for international).
'court' becomes 'ct' (abbreviation used in road names).
'dire' is an anagram of 'erdi'.
'int'+'ct'='intct'
'erdi' inserted within 'intct' is 'INTERDICT'.
(Other definitions for interdict that I've seen before include "Court order" , "Credit tin (anag) - ecclesiastical sanction" , "Decree" , "An authoritative prohibition, maybe by church" , "Ban" .)
