Bold prosecutor gets call (6)
I believe the answer is:
daring
'bold' is the definition.
(I've seen this in another clue)
'prosecutor gets call' is the wordplay.
'prosecutor' becomes 'D.A.' (District Attorney).
'gets' says to put letters next to each other.
'call' becomes 'ring' (telephone call).
'da'+'ring'='DARING'
(Other definitions for daring that I've seen before include "Adventurous courage" , "Challenging or defying" , "Venturesome" , "Derring-do" , "'Adventurous, bold (6)'" .)
