Outspread of liberally-minded actors (9)
I believe the answer is:
broadcast
'outspread' is the definition.
Both the definition and answer are adjectives. Perhaps you can see an association between them that I don't see?
'liberally-minded actors' is the wordplay.
'liberally minded' becomes 'broad' (I can't explain this - if you can you should believe this answer much more).
'actors' becomes 'cast' (group of actors).
'broad'+'cast'='BROADCAST'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for broadcast that I've seen before include "Transmit over airwaves" , "Send out over the airwaves" , "Put on the air" , "Sow" , "Transmit by radio or TV" .)
