Prosecutor breaks plaything now (5)
I believe the answer is:
today
'now' is the definition.
(I've seen this before)
'prosecutor breaks plaything' is the wordplay.
'prosecutor' becomes 'da' (D.A. is an example).
'breaks' means one lot of letters goes inside another.
'plaything' becomes 'toy' ('toy' can be a synonym of 'plaything').
'da' going within 'toy' is 'TODAY'.
(Other definitions for today that I've seen before include "Presently" , "Yesterday's tomorrow" , "Current period of 24 hours" , "one of our papers, once" , "Modern times" .)
