Cancellation of show containing empty rows (8)
I believe the answer is:
reversal
'cancellation' is the definition.
(thesaurus)
'show containing empty rows' is the wordplay.
'show' becomes 'reveal' (revealing is a kind of showing**).
'containing' is an insertion indicator.
'empty' means to remove the middle letters.
'rows' with its centre taken out is 'rs'.
'reveal' enclosing 'rs' is 'REVERSAL'.
'of' is the link.
(Other definitions for reversal that I've seen before include "Turnabout" , "change of heart" , "A set-back or turning around" , "Volte-face" , "Negation" .)
