Commotion as hairy hosts left (6)
I believe the answer is:
flurry
'commotion' is the definition.
(I know that flurry is a type of commotion)
'hairy hosts left' is the wordplay.
'hairy' becomes 'furry' (similar in meaning).
'hosts' means one lot of letters goes inside another (inserted letters are welcomed or hosted).
'left' becomes 'l' (common abbreviation).
'furry' going around 'l' is 'FLURRY'.
'as' is the link.
(Other definitions for flurry that I've seen before include "Light fall of snow" , "squall" , "Light snowfall" , "fall of snow, perhaps" , "Swirl of snow" .)
