Dance making supporter and man leave (8)
I believe the answer is:
fandango
'dance' is the definition.
(type of dance)
'supporter and man leave' is the wordplay.
'supporter' becomes 'fan' (fan is a kind of supporter).
'and' means one lot of letters go next to another.
'man' becomes 'dan' ().
'leave' becomes 'go' (to go is to depart or leave).
'fan'+'dan'+'go'='FANDANGO'
'making' acts as a link.
(Other definitions for fandango that I've seen before include "Spanish 2 Down" , "Lively Spanish dance" , "Spanish Steps" , "Old Spanish dance in triple time" , "Dance performed with castanets" .)
