Attorney initially raring to go wild and make an accusation (7)
I believe the answer is:
arraign
'make an accusation' is the definition.
'attorney initially raring to go wild' is the wordplay.
'initially' indicates taking the first letters.
'to go wild' is an anagram indicator (a wild or uncontrollable version of the letters).
The initial letter of 'attorney' is 'a'.
'raring' is an anagram of 'rraign'.
'a'+'rraign'='ARRAIGN'
'and' acts as a link.
(Other definitions for arraign that I've seen before include "Accuse of a wrong" , "Call to account" , "Accuse as in court" , "Summons" , "Call before court to answer criminal charge" .)
