Next US prosecutor turns judge with a little money (8)
I believe the answer is:
adjacent
'next' is the definition.
(synonyms)
'us prosecutor turns judge with a little money' is the wordplay.
'us prosecutor' becomes 'DA' (district attorney).
'turns' says the letters should be written backwards.
'judge' becomes 'J' (abbreviation for judge).
'with' means one lot of letters go next to another.
'little money' becomes 'cent' (coin of little value).
'da' in reverse letter order is 'ad'.
'ad'+'j'+'a'+'cent'='ADJACENT'
(Other definitions for adjacent that I've seen before include "Next (to something)" , "Abutting" , "Next-door" , "Lying near, bordering" , "Neither opposite nor hypotenuse?" .)
