I acted in variety show (8)
I believe the answer is:
indicate
'show' is the definition.
(I know that show can be written as indicate)
'i acted in variety' is the wordplay.
'variety' indicates anagramming the letters.
'acted'+'in'='actedin'
'actedin' with letters rearranged gives 'ndicate'.
'i'+'ndicate'='INDICATE'
(Other definitions for indicate that I've seen before include "Mark" , "Point out, make known" , "Point, show, signal" , "Point out, suggest" , "Make a signal" .)
