Play about District Attorney in the present time (5)
I believe the answer is:
today
'the present time' is the definition.
(thesaurus)
'play about district attorney' is the wordplay.
'play' becomes 'toy' ('toy' can be a synonym of 'play').
'about' means one lot of letters goes inside another.
'district attorney' becomes 'da' ('D.A.' can be a synonym of 'district attorney').
'toy' going around 'da' is 'TODAY'.
'in' is the link.
(Other definitions for today that I've seen before include "The present time or age" , "At the present time, in general" , "one of our papers, once" , "Modern times" , "Nowadays" .)
