Flipping jerk interrupts True in gig (7)
I believe the answer is:
recital
'gig' is the definition.
(I've seen this before)
'flipping jerk interrupts true' is the wordplay.
'flipping' shows that the letters should be reversed in order.
'jerk' becomes 'tic' (jerking movement by the body).
'interrupts' means one lot of letters goes inside another.
'true' becomes 'real' (synonyms).
'tic' reversed gives 'cit'.
'cit' placed into 'real' is 'RECITAL'.
'in' acts as a link.
(Other definitions for recital that I've seen before include "Narrative" , "Concert performance" , "Performance, usually musical" , "Public musical performance" , "Narration" .)
