Portray as the person the spectators are coming to see (4)
I believe the answer is:
draw
'portray' is the definition.
(to portray by drawing)
'the person the spectators are coming to see' is the wordplay.
I cannot really see how this works, but
'person' could be 'dr' (Dr is an example) and 'dr' is located in the answer.
'are' could be 'a' (short for 'are', historical unit of measurement) and 'a' is located in the answer.
A single letter 'w' remains which might be clued in a way I don't understand.
This explanation may well be incorrect...
'as' acts as a link.
Can you help me to learn more?
(Other definitions for draw that I've seen before include "No-winner result" , "Drag" , "Snag" , "Depict - raffle" , "Pull along; sketch" .)
