Scene is in lyric poem (7)
I believe the answer is:
episode
'scene' is the definition.
(thesaurus)
'is in lyric poem' is the wordplay.
'in' means one lot of letters goes inside another.
'lyric poem' becomes 'epode' (I've seen this in another clue).
'is' going into 'epode' is 'EPISODE'.
(Other definitions for episode that I've seen before include "Instalment; incident" , "Musical passage" , "Incident in a story or part of a serial" , "Part of a broadcast serial, say" , "One programme of a series" .)
