Donor at dance to make a big whip-round? (7)
I believe the answer is:
tornado
'a big whip-round?' is the definition.
(air that whips round)
'donor at dance' is the wordplay.
'dance' indicates anagramming the letters.
'donor'+'at'='donorat'
'donorat' with letters rearranged gives 'TORNADO'.
'to make' is the link.
(Other definitions for tornado that I've seen before include "Violent wind vortex" , "Severe wind" , "Funnel-shaped windstorm" , "Violent rotating windstorm" , "Dreadful blow" .)
