Stand for show again? (9)
I believe the answer is:
represent
This clue is a double definition.
'stand for' is the first definition.
('represent' can be a synonym of 'stand for')
'show again?' is the second definition.
('present' is an answer for 'show' so perhaps 'represent' is OK for 'show again')
(Other definitions for represent that I've seen before include "Speak on behalf" , "Picture" , "Stand for or symbolise" , "Serve as a symbol for" , "Explain" .)
