He's a shining figure (5)
I believe the answer is:
oscar
'a shining figure' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'he's' is the wordplay.
I cannot quite understand how this works, but
'he' could be 'car' and 'car' is located in the answer.
The remaining letters 'os' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for oscar that I've seen before include "to wit involved in row" , "Note" , "Title of Hollywood Academy award" , "Mr Wilde - film award" , "Boy" .)
