Acting group is bitter about shows (10)
I believe the answer is:
represents
'acting group is bitter' is the definition.
I can't tell whether this defines the answer.
'about shows' is the wordplay.
'about' becomes 're' ('re' means regarding or about).
'shows' becomes 'presents' ('present' can be a synonym of 'show').
're'+'presents'='REPRESENTS'
Can you help me to learn more?
(Other definitions for represents that I've seen before include "Portrays" , "plays" , "Stands for" , "shows" .)
