Twitch returned in actual concert (7)
I believe the answer is:
recital
'concert' is the definition.
(thesaurus)
'twitch returned in actual' is the wordplay.
'twitch' becomes 'tic' (tic is a kind of twitch).
'returned' shows that the letters should be reversed in order.
'in' indicates putting letters inside.
'actual' becomes 'real' ('real' can be a synonym of 'actual').
'tic' in reverse letter order is 'cit'.
'cit' placed inside 'real' is 'RECITAL'.
(Other definitions for recital that I've seen before include "Solo music performance" , "Chamber music concert" , "Reading" , "Musical entertainment or a long account" , "(Usually solo) concert" .)
