In the film world, an enviable figure (5)
I believe the answer is:
oscar
'figure' is the definition.
The definition and answer can be both related to communication as well as being singular nouns.
Maybe you can see an association between them that I don't see?
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for oscar that I've seen before include "Hollywood statuette given as annual award" , "Code word for O" , "Comms code for "O"" , "The familiar Mr Wilde, playwright" , "Film-prize statuette" .)
