A fan and he's holding something up (9)
I believe the answer is:
supporter
'a fan' is the definition.
(eg a fan of a football team)
'he's holding something up' is the wordplay.
I cannot quite see how this works, but
'up' is found in the answer.
'he' could be 'porter' and 'porter' is found in the answer.
A single letter 's' remains which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'and' is the link.
Can you help me to learn more?
(Other definitions for supporter that I've seen before include "sports fan?" , "Advocate" , "One helping" , "One cheers" , "Stay" .)
