Some brief answers for supporters (4)
I believe the answer is:
fans
'supporters' is the definition.
(fan is a kind of supporter)
'some brief answers for' is the wordplay.
'some' indicates the answer is hidden within the clue (some parts of the word are used).
'FANS' is hidden within 'brief answers for'.
(Other definitions for fans that I've seen before include "Devotees" , "Admirers" , "Aficionados" , "Devices for creating currents of air" , "They create currents of air" .)
