Attorney takes animal to the theatre (5)
I believe the answer is:
drama
'the theatre' is the definition.
(I've seen this before)
'attorney takes animal' is the wordplay.
'attorney' becomes 'D.A.' (District Attorney).
'takes' is an insertion indicator.
'animal' becomes 'ram' (male sheep).
'da' placed around 'ram' is 'DRAMA'.
'to' acts as a link.
(Other definitions for drama that I've seen before include "Exciting play or event" , "Emotional sequence of events (made out of a crisis?)" , "Turbulent emotional episode" , "Plays as a genre" , "Work to be performed by actors" .)
