Lyric connected with theatre (5)
I believe the answer is:
odeon
'theatre' is the definition.
(in ancient Greece)
'lyric connected' is the wordplay.
'lyric' becomes 'ode' (ode is a kind of lyric).
'connected' becomes 'on' (synonyms).
'ode'+'on'='ODEON'
'with' is the link.
(Other definitions for odeon that I've seen before include "Greek venue" , "Greek music hall" , "Ancient Greek theatre" , "Place for cinema or musical and dramatic performances" , "Do one (anag)" .)
